X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9463f27af643db333b74ce27d4caae760b273328;p=platform%2Fkernel%2Flinux-starfive.git

staging: rtl8188eu: Remove inline function rtw_inc_and_chk_continual_urb_error()

rtw_inc_and_chk_continual_urb_error() is used to check if device is
removed unexpectedly, to do that we can just check status of urb in
usb_read_port_complete() and usbctrl_vendorreq() doed that by checking
return value of usb_control_msg().
