Subject: [PATCH] ray_cs: remove redundant pointer 'p'
Date: Fri, 20 Jul 2018 19:07:40 +0100	[thread overview]
Message-ID: <20180720180740.21018-1-colin.king@canonical.com> (raw)

From: Colin Ian King <colin.king@canonical.com>

Pointer 'p' is being assigned but is never used hence it is
redundant and can be removed. Also re-work if statement to remove
redundant assignment of p.

Cleans up clang warning:
warning: variable 'p' set but not used [-Wunused-but-set-variable]
