[ Upstream commit 8dd29f19 ] The driver registers the watchdog with devm_watchdog_register_device() but still calls watchdog_unregister_device() on remove. Since clocks have to be stopped when removing the driver, after the watchdog device has been unregistered, we can not drop the call to watchdog_unregister_device(). Use watchdog_register_device() to register the watchdog. Fixes: 2bdf6acb ("watchdog: Add Realtek RTD1295") Cc: Andreas Färber <afaerber@suse.de> Signed-off-by:

[ Upstream commit f33e7bb3 ] Status of ADMA channel registers is not saved and restored during system suspend. During active playback if system enters suspend, this results in wrong state of channel registers during system resume and playback fails to resume properly. Fix this by saving following channel registers in runtime suspend and restore during runtime resume. * ADMA_CH_LOWER_SRC_ADDR * ADMA_CH_LOWER_TRG_ADDR * ADMA_CH_FIFO_CTRL * ADMA_CH_CONFIG * ADMA_CH_CTRL * ADMA_CH_CMD * ADMA_CH_TC Runtime PM calls will be inovked during system resume path if a playback or capture needs to be resumed. Hence above changes work fine for system suspend case. Fixes: f46b1957 ("dmaengine: tegra-adma: Add support for Tegra210 ADMA") Signed-off-by:

[ Upstream commit 5daab580 ] The kernel parameter igfx_off is used by users to disable DMA remapping for the Intel integrated graphic device.

[ Upstream commit 8f4426aa ] The QP transition optional parameters for the various transition for XRC QPs are identical to those for RC QPs. Many of the XRC QP transition optional parameter bits are missing from the QP optional mask table. These omissions caused failures when doing XRC QP state transitions. For example, when trying to change the response timer of an XRC receive QP via the RTS2RTS transition, the new timer value was ignored because MLX5_QP_OPTPAR_RNR_TIMEOUT bit was missing from the optional params mask for XRC qps for the RTS2RTS transition. Fix this by adding the missing XRC optional parameters for all QP transitions to the opt_mask table.

[ Upstream commit 3309bec8 ] The trace_hardirqs_on() sets current->hardirqs_enabled and from here the lockdep assumes interrupts are enabled although they are remain disabled until the context switches to the guest. Consequent srcu_read_lock() checks the flags in rcu_lock_acquire(), observes disabled interrupts and prints a warning (see below). This moves trace_hardirqs_on/off closer to __kvmppc_vcore_entry to prevent lockdep from being confused.

[ Upstream commit 4be5975a ] Further fix the file locking in the afs filesystem client in a number of ways, including: (1) Don't submit the operation to obtain a lock from the server in a work queue context, but rather do it in the process context of whoever issued the requesting system call. (2) The owner of the file_lock struct at the front of the pending_locks queue now owns right to talk to the server. (3) Write locks can be instantly granted if they don't overlap with any other locks *and* we have a write lock on the server. (4) In the event of an authentication/permission error, all other matching pending locks requests are also immediately aborted. (5) Properly use VFS core locks_lock_file_wait() to distribute the server lock amongst local client locks, including waiting for the lock to become available. Test with: sqlite3 /afs/.../scratch/billings.sqlite <<EOF CREATE TABLE hosts ( hostname varchar(80), shorthost varchar(80), room varchar(30), building varchar(30), PRIMARY KEY(shorthost) ); EOF With the version of sqlite3 that I have, this should fail consistently with EAGAIN, whether or not the program is straced (which introduces some delays between lock syscalls).

[ Upstream commit 68ce801f ] Fix AFS file locking to allow fine grained locks as some applications, such as firefox, won't work if they can't take such locks on certain state files - thereby preventing the use of kAFS to distribute a home directory. Note that this cannot be made completely functional as the protocol only has provision for whole-file locks, so there exists the possibility of a process deadlocking itself by getting a partial read-lock on a file first and then trying to get a non-overlapping write-lock - but we got the server's read lock with the first lock, so we're now stuck. OpenAFS solves this by just granting any partial-range lock directly without consulting the server - and hoping there's no remote collision. I want to implement that in a separate patch and it requires a bit more thought. Fixes: 8d6c554126b8 ("AFS: implement file locking") Reported-by:

[ Upstream commit 648865a7 ] In 2D transfers (for the AXI DMAC), the number of frames (numf) represents Y_LENGTH, and the length of a frame is X_LENGTH. 2D transfers are useful for video transfers where screen resolutions ( X * Y ) are typically aligned for X, but not for Y. There is no requirement for Y_LENGTH to be aligned to the bus-width (or anything), and this is also true for AXI DMAC. Checking the Y_LENGTH for alignment causes false errors when initiating DMA transfers. This change fixes this by checking only that the Y_LENGTH is non-zero.

[ Upstream commit c7861adb ] Each eTSEC MAC has its own TBI (SGMII) PCS and private MDIO bus. But due to a DTS oversight, both SGMII-compatible MACs of the LS1021 SoC are pointing towards the same internal PCS. Therefore nobody is controlling the internal PCS of eTSEC0. Upon initial ndo_open, the SGMII link is ok by virtue of U-boot initialization. But upon an ifdown/ifup sequence, the code path from ndo_open -> init_phy -> gfar_configure_serdes does not get executed for the PCS of eTSEC0 (and is executed twice for MAC eTSEC1). So the SGMII link remains down for eTSEC0. On the LS1021A-TWR board, to signal this failure condition, the PHY driver keeps printing '803x_aneg_done: SGMII link is not ok'. Also, it changes compatible of mdio0 to "fsl,etsec2-mdio" to match mdio1 device. Fixes: 055223d4 ("ARM: dts: ls1021a: Enable the eTSEC ports on QDS and TWR") Signed-off-by:

[ Upstream commit 7893f9e1 ] Some tcpc device-drivers need to explicitly be told to watch for connection events, otherwise the tcpc will not generate any TCPM_CC_EVENTs and devices being plugged into the Type-C port will not be noticed. For dual-role ports tcpm_start_drp_toggling() is used to tell the tcpc to watch for connection events. Sofar we lack a similar callback to the tcpc for single-role ports. With some tcpc-s such as the fusb302 this means no TCPM_CC_EVENTs will be generated when the port is configured as a single-role port. This commit renames start_drp_toggling to start_toggling and since the device-properties are parsed by the tcpm-core, adds a port_type parameter to the start_toggling callback so that the tcpc_dev driver knows the port-type and can act accordingly when it starts toggling. The new start_toggling callback now always gets called if defined, instead of only being called for DRP ports. To avoid this causing undesirable functional changes all existing start_drp_toggling implementations are not only renamed to start_toggling, but also get a port_type check added and return -EOPNOTSUPP when port_type is not DRP.

[ Upstream commit 4bcd4ec1 ] We find that sysctl_tipc_rmem and named_timeout do not have the right minimum setting. sysctl_tipc_rmem should be larger than zero, like sysctl_tcp_rmem. And named_timeout as a timeout setting should be not less than zero.

[ Upstream commit 98e26302 ] Currently the kfree of output.pointer can be potentially freeing an uninitalized pointer in the case where out_data is NULL. Fix this by reworking the case where out_data is not-null to perform the ACPI status check and also the kfree of outpoint.pointer in one block and hence ensuring the pointer is only freed when it has been used. Also replace the if (ptr != NULL) idiom with just if (ptr). Fixes: ff0e9f26 ("platform/x86: alienware-wmi: Correct a memory leak") Signed-off-by:

[ Upstream commit 421db1ab ] commit beb4641a ("PCI: dwc: Add MSI-X callbacks handler") while adding MSI-X callback handler, introduced dw_pcie_ep_find_capability() and __dw_pcie_ep_find_next_cap() for finding the MSI and MSIX capability. However if MSI or MSIX capability is the last capability (i.e there are no additional items in the capabilities list and the Next Capability Pointer is set to '0'), __dw_pcie_ep_find_next_cap will return '0' even though MSI or MSIX capability may be present because of incorrect ordering of the "next_cap_ptr" check. Fix it. Fixes: beb4641a ("PCI: dwc: Add MSI-X callbacks handler") Signed-off-by:
