Subject: [PATCH] drm/msm/dpu: remove unused variable cmd_enc
Message-ID: <20210521041633.GA1747@raspberrypi>
MIME-Version: 1.0
Content-Type: text/plain; charset=utf-8

User-Agent: Mutt/1.10.1 (2018-07-13)
Precedence: bulk

After the call to to_dpu_encoder_phys_cmd() is made,
'cmd_enc' is not used. Where to_dpu_encoder_phys_cmd() is simply replaced with
container_of(x, struct dpu_encoder_phys_cmd, base) by compiler.

So it had better remove W=1 kernel build warning(s):

  drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_cmd.c: In function
 ‘dpu_encoder_phys_cmd_wait_for_commit_done’:
  drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_cmd.c:688:31: warning:
  variable ‘cmd_enc’ set but not used
