Subject: [PATCH 6/9] drm/bridge: tc358767: Simplify error check in tc_aux_linx_setup()
Date: Tue, 26 Feb 2019 11:36:06 -0800	[thread overview]
Message-ID: <20190226193609.9862-7-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20190226193609.9862-1-andrew.smirnov@gmail.com>

Tc_poll_timeout() can only return -ETIMEDOUT, so checking for other
errors is not necessary. Drop it. No functional change intended.
