Subject: 9p: return NULL when trans not found
X-Git-Tag: v2.6.24-rc2~2^2~1
X-Git-Url: http://bbs.cooldavid.org/git/?a=commitdiff_plain;h=dd1a458412c358f8b4550d7e7df88982c88ce408;p=net-next-2.6.git

9p: return NULL when trans not found

v9fs_match_trans function returns arbitrary transport module instead of NULL
when the requested transport is not registered. This patch modifies the
function to return NULL in that case.
