[PATCH] VPU: mediatek: fix simple_open.cocci warnings

From: Julia Lawall
Date: Fri Apr 22 2016 - 09:12:39 EST


Remove an open coded simple_open() function
and replace file operations references to the function
with simple_open() instead.

I'm just passing this along. Simple_open additionally has a check that
inode->i_private is not NULL, before doing the assignment. I don't know
if that difference is important in this case.
