Subject: [PATCH 2/7] drivers/gpu: Use kzalloc for allocating only one thing
Date: Sat, 19 Dec 2009 08:16:33 +0100 (CET) [thread overview]
Message-ID: <Pine.LNX.4.64.0912190816140.30546@ask.diku.dk> (raw)
From: Julia Lawall <julia@diku.dk>
Use kzalloc rather than kcalloc(1,...)
The use of the allocated memory that looks like an array is &p->relocs[0],
but this should be the same as p->relocs.
The semantic patch that makes this change is as follows:
