The "translate_scan" function in rtl8712 uses a lot of stack, and gets inlined into its single caller, r8711_wx_get_scan, which in some configurations now blows the 1024 byte stack warning limit: drivers/staging/rtl8712/rtl871x_ioctl_linux.c: In function 'r8711_wx_get_scan': drivers/staging/rtl8712/rtl871x_ioctl_linux.c:1227:1: error: the frame size of 1032 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] This somewhat reduces the stack usage by moving the translate_scan function out of line with the noinline_for_stack annotation. It might be possible to modify translate_scan() a little further to reduce the stack usage, but with this patch, we can build without the warning, the the call chain to get here is rather predictable (sys_ioctl->vfs_ioctl->sock_ioctl->dev_ioctl->wext_ioctl-> r8711_wx_get_scan).

Fix a driver hang caused by earlier suspend/resume cycles. By handling a ENODEV error during suspend as a real error we eventually end up stopping the whole driver. Fix this by handling the ENODEV error (during suspend) essentially by retrying. Signed-off-by:

Declare rtl871x_intf_resume() function static since it is defined and called in this file only. This fixes the following sparse warning: warning: symbol 'rtl871x_intf_resume' was not declared. Should it be static? Signed-off-by:

For platform_driver, we don't need to set .owner field as is set by platform driver core. The semantic patch used here first checks whether platform_driver struct was actually used in a call to set the .owner field.

We have only one NAPI poll running at a time, so virtual port rx counters can be updated normally. Update of rx_dropped can still race with the gathering of statistics, but full accuracy is not required there. Signed-off-by:

With cmwq, use of dedicated workqueues can be replaced by system_wq. Removed the dedicated workqueue and used system_wq instead. Since the work items in the workqueues do not need to be ordered, increase of concurrency by switching to system_wq should not break anything. All work items are sync canceled so it is guaranteed that no work is running when driver is detached. Signed-off-by:

With concurrency managed workqueues, use of dedicated workqueues can be replaced by using system_wq. Drop schedule_usb_work by using system_wq. Since there is only one work item per buf_anchor and most_dev and they do not need to be ordered, increase of concurrency by switching to system_wq should not break anything. Both work items are sync canceled before the driver can be unregistered, to ensure no work item is pending or executing on any CPU by the time exit path is in flight. Signed-off-by:

Devm_ functions allocate memory that is released when a driver detaches. Replace request_mem_region and ioremap with devm_ioremap_resource and remove corresponding freeing functions release_mem_region and iounmap from probe and remove functions of a platform device. Also, an unnecessary platform_set_drvdata() has been removed since the driver core clears the driver data to NULL after device release or on probe failure. There is no need to manually clear the device driver data to NULL. Lastly, unnecessary labels have been removed. Signed-off-by:
