This patch changes the kernel-doc style comment block to common comment block. These files don't support kernel-doc style so no need to use the kernel-doc style. Also, they cause the warning when W=1 option is used as below. drivers/bluetooth/hci_ll.c:518: warning: Function parameter or member 'lldev' not described in 'download_firmware' drivers/bluetooth/btmrvl_debugfs.c:29: warning: cannot understand function prototype: 'struct btmrvl_debugfs_data ' drivers/bluetooth/btmrvl_sdio.c:36: warning: expecting prototype for Marvell BT-over-SDIO driver().

The driver has to issue the specific command to enable Bluetooth SCO over the I2S/PCM interface on mt7921s, that is supported since the firmware with version 20211222191101 was added, and the patch would not cause any harm even when the old firmware is applied. The SCO profile with the patch was tested by setting up a VOIP application, connected to HFP device, checked telephony function can work normally. Co-developed-by:

Enable wake on bluetooth on mt7921s that can be supported since the firmware with version 20211129211059 was added, and the patch would not cause any harm even when the old firmware is applied. The patch was tested by setting up an HID or HOGP profile to connect a Bluetooth keyboard and mouse, then putting the system to suspend, then trying to wake up the system by moving the Bluetooth keyboard or mouse, and then checking if the system can wake up and be brought back to the normal state.

As stated in [1], dma_set_mask() with a 64-bit mask never fails if dev->dma_mask is non-NULL. So, if it fails, the 32 bits case will also fail for the same reason.

So qlcnic_set_dma_mask(), (in qlcnic_main.c) can be simplified a lot and inlined directly in its only caller. If dma_set_mask_and_coherent() succeeds, 'pci_using_dac' is known to be 1. So it can be removed from all the calling chain. qlcnic_setup_netdev() can finally be simplified as-well. [1]: https://lkml.org/lkml/2021/6/7/398Signed-off-by:

Syzbot reported uninit value in mcs7830_bind(). The problem was in missing validation check for bytes read via usbnet_read_cmd(). usbnet_read_cmd() internally calls usb_control_msg(), that returns number of bytes read. Code should validate that requested number of bytes was actually read. So, this patch adds missing size validation check inside mcs7830_get_reg() to prevent uninit value bugs Reported-and-tested-by: syzbot+003c0a286b9af5412510@syzkaller.appspotmail.com Fixes: 2a36d708 ("USB: driver for mcs7830 (aka DeLOCK) USB ethernet adapter") Signed-off-by:

Menglong Dong says: ==================== net: skb: introduce kfree_skb_with_reason() In this series patch, the interface kfree_skb_with_reason() is introduced(), which is used to collect skb drop reason, and pass it to 'kfree_skb' tracepoint. Therefor, 'drop_monitor' or eBPF is able to monitor abnormal skb with detail reason. In fact, this series patches are out of the intelligence of David and Steve, I'm just a truck man :/ Previous discussion is here: https://lore.kernel.org/netdev/20211118105752.1d46e990@gandalf.local.home/ https://lore.kernel.org/netdev/67b36bd8-2477-88ac-83a0-35a1eeaf40c9@gmail.com/ In the first patch, kfree_skb_with_reason() is introduced and the 'reason' field is added to 'kfree_skb' tracepoint. In the second patch, 'kfree_skb()' in replaced with 'kfree_skb_with_reason()' in tcp_v4_rcv(). In the third patch, 'kfree_skb_with_reason()' is used in __udp4_lib_rcv(). Changes since v3: - fix some code style problems in skb.h Changes since v2: - rename kfree_skb_with_reason() to kfree_skb_reason() - make kfree_skb() static inline, as Jakub suggested Changes since v1: - rename some drop reason, as David suggested - add the third patch ==================== Link: https://lore.kernel.org/r/20220109063628.526990-1-imagedong@tencent.comSigned-off-by:

Introduce the interface kfree_skb_reason(), which is able to pass the reason why the skb is dropped to 'kfree_skb' tracepoint. Add the 'reason' field to 'trace_kfree_skb', therefor user can get more detail information about abnormal skb with 'drop_monitor' or eBPF. All drop reasons are defined in the enum 'skb_drop_reason', and they will be print as string in 'kfree_skb' tracepoint in format of 'reason: XXX'. ( Maybe the reasons should be defined in a uapi header file, so that user space can use them? ) Signed-off-by:
