Looks like 24xx uses mode3 instead of mode4 for muxable GPIO pins. This will be needed when 24xx mux code is converted to use the new mux functions. Signed-off-by: -

futex_find_get_task is currently used (through lookup_pi_state) from two contexts, futex_requeue and futex_lock_pi_atomic. None of the paths looks it needs the credentials check, though. Different (e)uids shouldn't matter at all because the only thing that is important for shared futex is the accessibility of the shared memory. The credentail check results in glibc assert failure or process hang (if glibc is compiled without assert support) for shared robust pthread mutex with priority inheritance if a process tries to lock already held lock owned by a process with a different euid: pthread_mutex_lock.c:312: __pthread_mutex_lock_full: Assertion `(-(e)) != 3 || !robust' failed. The problem is that futex_lock_pi_atomic which is called when we try to lock already held lock checks the current holder (tid is stored in the futex value) to get the PI state. It uses lookup_pi_state which in turn gets task struct from futex_find_get_task. ESRCH is returned either when the task is not found or if credentials check fails. futex_lock_pi_atomic simply returns if it gets ESRCH. glibc code, however, doesn't expect that robust lock returns with ESRCH because it should get either success or owner died.

On fsg_unbind the common->fsg pointer was not NULLed if the unbound fsg_dev instance was the current one. As an effect, the incorrect pointer was preserved in all further operations which caused do_set_interface to reference an invalid region. This commit fixes this by raising an exception in fsg_bind which will change the common->fsg pointer. This also requires an wait queue so that the thread in fsg_bind can wait till the worker thread handles the exception. This commit removes also a config and new_config fields of fsg_common as they are no longer needed since fsg can be used to determine whether function is active or not. Moreover, this commit removes possible race condition where the fsg field was modified in both the worker thread and form various other contexts. This is fixed by replacing prev_fsg with new_fsg. At this point, fsg is assigned only in worker thread. Signed-off-by:

The full speed descriptors were copied to the usb_function structure in the fsg_bind_config function before call to the usb_ep_autoconfig. The usb_ep_autoconfig was called in fsg_bind using the original descriptors. In effect copied descriptors were not updated. This patch changes the copy full speed descriptors after the call to usb_op_autoconfig is performed. This way, copied full speed descriptors have updated values. Signed-off-by:

Setting MUSB Burst Mode 3 automatically enables support for lower burst modes (BURST4, BURST8, BURST16 or bursts of unspecified length). There is no need to set these burst modes based on the packet size. Also enable the burst mode for both mode1 and mode0. This is a fix for buggy hardware - having the lower burst modes enabled can potentially cause lockups of the DMA engine used in OMAP2/3/4 chips. Signed-off-by:

Attempt to build MUSB driver with CONFIG_PM=y (e.g. in the OTG mode) on DaVinci results in these link errors: drivers/built-in.o: In function `musb_restore_context': led-triggers.c:(.text+0x714d8): undefined reference to `musb_platform_restore_context' drivers/built-in.o: In function `musb_save_context': led-triggers.c:(.text+0x71788): undefined reference to `musb_platform_save_context' This turned out to be caused by commit 9957dd97 (usb: musb: Fix compile error for omaps for musb_hdrc). Revert it, taking into account the rename of CONFIG_ARCH_OMAP34XX into CONFIG_ARCH_OMAP3 (which that commit fixed in a completely inappropriate way) and the recent addition of OMAP4 support.

This patch (as1403) is a partial reversion of an earlier change (commit 5f677f1d "USB: fix remote wakeup settings during system sleep"). After hearing from a user, I realized that remote wakeup should be enabled during system sleep whenever userspace allows it, and not only if a driver requests it too. Indeed, there could be a device with no driver, that does nothing but generate a wakeup request when the user presses a button. Such a device should be allowed to do its job. The problem fixed by the earlier patch -- device generating a wakeup request for no reason, causing system suspend to abort -- was also addressed by a later patch ("USB: don't enable remote wakeup by default", accepted but not yet merged into mainline). The device won't be able to generate the bogus wakeup requests because it will be disabled for remote wakeup by default. Hence this reversion will not re-introduce any old problems. Signed-off-by:

Stanse found that isp1362_sw_reset tries to take a isp1362_hcd->lock, but it is already held in isp1362_hc_stop. Avoid that by introducing __isp1362_sw_reset which doesn't take the lock and call it from isp1362_hc_stop. isp1362_sw_reset is then as simple as lock -- __isp1362_sw_reset -- unlock. Signed-off-by:

As a part of aligning the ISR code for MUSB with the specs, the ISR code was re-written. See Commit 1c25fda4 (usb: musb: handle irqs in the order dictated by programming guide) With this the suspend interrupt came accidently under CONFIG_USB_MUSB_HDRC_HCD. The fix brings suspend interrupt handling outside CONFIG_USB_MUSB_HDRC_HCD. Signed-off-by:

Commit 6c12db90 introduced a bug for control transfers. The patch was supposed to change when the link TRBs at the end of each ring segment were given to the hardware. If a transfer descriptor (TD) ended just before the link TRB, the code wouldn't give back the link TRB to the hardware; instead it would be given back in prepare_ring() just before the next TD was enqueued at the top of the ring. Unfortunately, the code relied on checking the chain bit of the TRB to determine whether the TD ended just before the link TRB. It assumed that the ring enqueuing code would call prepare_ring() before enqueuing the next TD. However, control transfers are made of multiple TDs, and prepare_ring() is only called once before enqueuing two or three TDs. If the first or second TD of the control transfer ended just before the link TRB, then the code in inc_enq() would not move the enqueue pointer past the link TRB, and the link TRB would get overwritten. This would cause the xHCI driver to start writing to memory past the ring segment, and eventually the system would crash or hang. The fix is to add a flag to inc_enq() that says whether the caller will enqueue more TDs before calling prepare_ring(). If the chain bit is cleared (meaning this is the last TRB in a TD), and the caller will not enqueue more TDs, then we defer giving back the link TRB. Signed-off-by:

During __gfs_do_config() some invalid pointers may be left in usb_configuration::interfaces array from previous calls to the __gfs_do_config() for the same configuration. This will always happen if an user space function which has a fewer then the last user space function registers itself. Composite's set_config() function that a pointer after the last interface in usb_configuration::interface is NULL unless the array is full. This patch makes the __gfs_do_config() make sure that if the usb_configuration::interface is not full then a pointer after the last interface is NULL. Signed-off-by:
