Larry Finger 37b12dd2b0 rtl8187: Fix kernel oops when device is removed when LEDS enabled ... As reported by Rick Farina (sidhayn@gmail.com), removing the RTL8187 USB stick, or unloading the driver rtl8187 using rmmod will cause a kernel oops. There are at least two forms of the failure, (1) BUG: Scheduling while atomic, and (2) a fatal kernel page fault. This problem is reported in Bugzilla #14539. This problem does not occur for kernel 2.6.31, but does for 2.6.32-rc2, thus it is technically a regression; however, bisection did not locate any faulty patch. The fix was found by comparing the faulty code in rtl8187 with p54usb. My interpretation is that the handling of work queues in mac80211 changed enough to the LEDs to be unregistered before tasks on the work queues are cancelled. Previously, these actions could be done in either order. (Herton Ronaldo Krzesinski <herton@mandriva.com.br> reports that the code is the same in 2.6.31, so this may be a candidate for 2.6.31.x. -- JWL) Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Reported-by: Rick Farina <sidhayn@gmail.com> Tested-by: Rick Farina <sidhayn@gmail.com> Cc: stable@kernel.org Signed-off-by: John W.
