From: Ben Hutchings Date: Fri, 9 Jul 2010 09:12:41 +0000 (+0000) Subject: net: Document that dev_get_stats() returns the given pointer X-Git-Tag: v3.12-rc1~9497^2~287 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d77535162e736c47978d5c01469c56e1781dc91b;p=kernel%2Fkernel-generic.git net: Document that dev_get_stats() returns the given pointer Document that dev_get_stats() returns the same stats pointer it was given. Remove const qualification from the returned pointer since the caller may do what it likes with that structure. Signed-off-by: Ben Hutchings Signed-off-by: David S.
