Subject: [PATCH 1/1] net: mdio: mux-bcm-iproc: Use alignment helpers and SZ_4K
Date: Fri, 29 Dec 2023 16:52:32 +0200	[thread overview]
Message-ID: <20231229145232.6163-1-ilpo.jarvinen@linux.intel.com> (raw)

Instead of open coding, use IS_ALIGNED() and ALIGN_DOWN() when dealing
with alignment. Replace also literals with SZ_4K.
