Subject: cred: use 'const' in get_current_{user,groups}
X-Git-Tag: firefly_0821_release~3680^2~4690
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=638a8439096c582bdb523fcea9d875d3e1fed38a;p=firefly-linux-kernel-4.4.55.git

cred: use 'const' in get_current_{user,groups}

Avoid annoying warnings from these functions ("discards qualifiers")
because they assign 'current_cred()' to a non-const pointer.
