[PATCH] staging: android: logger: fix kuid/uid in logger_entry

From: Xiong Zhou
Date: Wed Oct 29 2014 - 22:23:51 EST


From: Xiong Zhou <jencce.kernel@xxxxxxxxx>

struct logger_entry can be returned to userspace via ioctl,
so it is wrong to have a kuid_t member, fixing it to uid_t.
This was introduced by commit bd471258f2, to pass uidguid
type checks : UIDGID_STRICT_TYPE_CHECKS, which has been
removed from kernel in commit 261000a56b6.

Fixes: bd471258f2 (logger: use kuid_t instead of uid_t)
Signed-off-by: Xiong Zhou <jencce.kernel@xxxxxxxxx>
