Subject: [PATCH] VPU: mediatek: fix simple_open.cocci warnings
Date: Fri, 22 Apr 2016 15:12:19 +0200 (CEST)	[thread overview]
Message-ID: <alpine.DEB.2.10.1604221509350.2872@hadrien> (raw)

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

Generated by: scripts/coccinelle/api/simple_open.cocci

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.
