Subject: [PATCH 1/2] ieee802154: mcr20a: Replace magic number with constants
Date: Fri, 31 Aug 2018 23:46:41 +0200 [thread overview]
Message-ID: <20180831214642.30711-2-liuxuenetmail@gmail.com> (raw)
In-Reply-To: <20180831214642.30711-1-liuxuenetmail@gmail.com>
The combination of defined constants are used to present the
state of IRQ so the magic numbers has been replaced.
This is a simple coding style change which should have no impact on
runtime code execution.
