Subject: [PATCH v2 04/17] i2c: tegra: Don't ignore tegra_i2c_flush_fifos() error
Date: Wed,  2 Sep 2020 00:10:49 +0300	[thread overview]
Message-ID: <20200901211102.11072-5-digetx@gmail.com> (raw)
In-Reply-To: <20200901211102.11072-1-digetx@gmail.com>

The tegra_i2c_flush_fifos() may fail and transfer should be aborted in
this case.
