From 94fd8405ea62bd2d4a40f3013e8e6935b6643235 Mon Sep 17 00:00:00 2001 From: David Howells Date: Mon, 28 Jun 2010 14:05:04 +0100 Subject: KEYS: Use the variable 'key' in keyctl_describe_key() keyctl_describe_key() turns the key reference it gets into a usable key pointer and assigns that to a variable called 'key', which it then ignores in favour of recomputing the key pointer each time it needs it. Make it use the precomputed pointer instead. Without this patch, gcc 4.6 reports that the variable key is set but not used: building with gcc 4.6 I'm getting a warning message: CC security/keys/keyctl.o security/keys/keyctl.c: In function 'keyctl_describe_key': security/keys/keyctl.c:472:14: warning: variable 'key' set but not used Reported-by: Justin P.
