[PATCH 3.2 076/152] video/fbdev: fix defio's fsync

From: Ben Hutchings
Date: Mon Feb 16 2015 - 21:27:46 EST


3.2.67-rc1 review patch. If anyone has any objections, please let me know.

------------------

From: Tomi Valkeinen <tomi.valkeinen@xxxxxx>

commit 30ea9c5218651bc11cbdba7820be78f04e2d83bc upstream.

fb_deferred_io_fsync() returns the value of schedule_delayed_work() as
an error code, but schedule_delayed_work() does not return an error. It
returns true/false depending on whether the work was already queued.

Fix this by ignoring the return value of schedule_delayed_work().
