usb: gadget: f_fs: stop sleeping in ffs_func_eps_disable

2016-11-21T09:11:38Z

commit a9e6f83c2df199187a5248f824f31b6787ae23ae upstream. ffs_func_eps_disable is called from atomic context so it cannot sleep thus cannot grab a mutex. Change the handling of epfile->read_buffer to use non-sleeping synchronisation method.

usb: gadget: f_fs: edit epfile->ep under lock

2016-11-21T09:11:38Z

commit 454915dde06a51133750c6745f0ba57361ba209d upstream. epfile->ep is protected by ffs->eps_lock (not epfile->mutex) so clear it while holding the spin lock. Tested-by: John Stultz Tested-by: Chen Yu Signed-off-by: Michal Nazarewicz Signed-off-by: Felipe Balbi Signed-off-by: Greg Kroah-Hartman
