Subject: rt2x00: configure_filter() callback is allowed to sleep
X-Git-Tag: v2.6.32-rc1~703^2~335^2~40
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=afa620429ac6a636246f85d97cf205d6533e7fcb;p=platform%2Fkernel%2Flinux-exynos.git

rt2x00: configure_filter() callback is allowed to sleep

The configure_filter() callback function no longer needs
to be atomic. Remove the scheduled work structure and
call into the driver configure_filter() directly.
