Subject: [PATCH] gpu: ipu-v3: ipu-dc: Remove unused 'di' variable
Date: Sat, 16 Sep 2017 21:58:51 -0300 [thread overview]
Message-ID: <1505609931-23532-1-git-send-email-festevam@gmail.com> (raw)
From: Fabio Estevam <fabio.estevam@nxp.com>
The 'di' variable is never used inside lipu_dc_enable_channel(),
so just remove it.
This fixes the following build warning with W=1:
drivers/gpu/ipu-v3/ipu-dc.c: In function 'ipu_dc_enable_channel':
drivers/gpu/ipu-v3/ipu-dc.c:252:6: warning: variable 'di' set but not used [-Wunused-but-set-variable]
