Subject: [PATCH v8 04/32] i2c: tegra: Mask interrupt in tegra_i2c_issue_bus_clear()
Date: Wed, 23 Sep 2020 01:51:27 +0300	[thread overview]
Message-ID: <20200922225155.10798-5-digetx@gmail.com> (raw)
In-Reply-To: <20200922225155.10798-1-digetx@gmail.com>

The tegra_i2c_issue_bus_clear() may fail and in this case BUS_CLR_DONE
stays unmasked. Hence let's mask it for consistency. This patch doesn't
fix any known problems.
