Subject: [PATCH v2 14/17] i2c: tegra: Improve coding style of tegra_i2c_wait_for_config_load()
Date: Wed, 2 Sep 2020 00:10:59 +0300 [thread overview]
Message-ID: <20200901211102.11072-15-digetx@gmail.com> (raw)
In-Reply-To: <20200901211102.11072-1-digetx@gmail.com>
Improve coding style of the tegra_i2c_wait_for_config_load() function by
making code a bit more narrow, adhering to the common kernel coding style.
