Subject: Staging: hv: Remove check for NULL before calling kfree()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1e19c054434c7d3ad618129c2ff5c3d81efa6949;p=linux-beck.git

Staging: hv: Remove check for NULL before calling kfree()

kfree() knows how to deal with NULL, so there's no reason to check for
NULL before passing something to it.
