Subject: [PATCH 1/3] ACPICA: Introduce ACPI_ACCESS_BIT_WIDTH() macro
Date: Wed, 12 Feb 2020 14:05:38 +0300 [thread overview]
Message-ID: <20200212110540.83559-1-mika.westerberg@linux.intel.com> (raw)
In-Reply-To: <20200211180331.11dbe525@endymion>
Sometimes it is useful to find the access_width field value in bytes and
not in bits so add a helper that can be used for this purpose.
