Subject: [PATCH v3 11/22] i2c: tegra: Remove likely/unlikely from the code
Date: Thu, 3 Sep 2020 03:52:49 +0300 [thread overview]
Message-ID: <20200903005300.7894-12-digetx@gmail.com> (raw)
In-Reply-To: <20200903005300.7894-1-digetx@gmail.com>
The likely/unlikely annotations should be used only in a hot paths of
performance-critical code. The I2C driver doesn't have such paths, and
thus, there is no justification for usage of likely/unlikely annotations
in the code. Hence remove them.
