Subject: [PATCH][scsi-next] scsi: aacraid: remove redundant setting of variable c
Date: Fri,  5 Jan 2018 15:31:06 +0000	[thread overview]
Message-ID: <20180105153106.17605-1-colin.king@canonical.com> (raw)

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

A previous commit no longer stores the contents of c, so we now have
a situation where c is being updated but the value is never read. Clean
up the code by removing the now redundant setting of variable c.

Cleans up clang warning:
drivers/scsi/aacraid/aachba.c:943:3: warning: Value stored to 'c' is
never read

Fixes: f4e8708d3104 ("scsi: aacraid: Fix udev inquiry race condition")
