Subject: [IPCOMP6]: don't check vfree() argument for NULL.
X-Git-Tag: v2.6.17-rc1~1175^2~187
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2b191befe2c47c2f6e96b836a1f6054c9cbc4a0b;p=platform%2Fkernel%2Flinux-3.10.git

[IPCOMP6]: don't check vfree() argument for NULL.

vfree does it's own NULL checking, so checking a pointer before
handing it to vfree is pointless.
