Subject: [PATCH v2 4/7] i2c: designware: Drop unneeded condition in i2c_dw_validate_speed()
Date: Tue, 19 May 2020 15:50:40 +0300 [thread overview]
Message-ID: <20200519125043.6069-4-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20200519125043.6069-1-andriy.shevchenko@linux.intel.com>
We may bailout directly from the loop instead of breaking it and
testing a loop counter. This also gives advantages such as decreased
indentation level along with dropped unneeded condition.
