Subject: cred: use 'const' in get_current_{user,groups}
X-Git-Tag: MMI-PSA29.97-13-9~18611
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=638a8439096c582bdb523fcea9d875d3e1fed38a;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.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.
