Subject: [PATCH v3 07/14] spi: Use BITS_TO_BYTES()
Date: Tue, 11 Jul 2023 20:17:49 +0300 [thread overview]
Message-ID: <20230711171756.86736-8-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20230711171756.86736-1-andriy.shevchenko@linux.intel.com>
BITS_TO_BYTES() is the existing macro which takes care about full
bytes that may fully hold the given amount of bits. Use it.
