Subject: [PATCH] arm: mach-davinci: use kzalloc()
Date: Sat, 06 Aug 2011 13:26:13 +0200

Use kzalloc rather than kmalloc followed by memset with 0
This considers some simple cases that are common and easy to validate
Note in particular that there are no ...s in the rule, so all of the
matched code has to be contiguous
The semantic patch that makes this output is available
in scripts/coccinelle/api/alloc/kzalloc-simple.cocci.
More information about semantic patching is available at
