Subject: [PATCH v1 2/3] regmap: mmio: Use swabXX_array() helpers
Date: Wed, 31 Aug 2022 17:54:06 +0300	[thread overview]
Message-ID: <20220831145407.78166-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20220831145407.78166-1-andriy.shevchenko@linux.intel.com>

Since we have a few helpers to swab elements of a given size in an array
use them instead of open coded variants.
