Subject: [PATCH] arm: mach-omap2: remove superfluous NULL pointer check
Date: Sun, 22 Mar 2015 01:00:18 +0100	[thread overview]
Message-ID: <1426982418-9649-1-git-send-email-stefan@agner.ch> (raw)

The NULL pointer check for superset->muxnames will always evaluate
true since muxnames is an array within struct omap_mux. Remove the
superfluous check to avoid warnings when using LLVM/clang.

Signed-off-by: Stefan Agner <stefan@agner.ch>

For the reference, the warning generated by LLVM/clang:
arch/arm/mach-omap2/mux.c:1056:18: warning: address of array
'superset->muxnames' will always evaluate to 'true' [-Wpointer-bool-conversion]
                if (!superset->muxnames || !superset->muxnames[0]) {
