Subject: [PATCH] mmc: tmio: do not print real IOMEM pointer
Date: Mon, 16 Nov 2020 17:42:52 +0100 [thread overview]
Message-ID: <20201116164252.44078-1-krzk@kernel.org> (raw)

memory layout. This fixes smatch warning:
drivers/mmc/host/tmio_mmc.c:177 tmio_mmc_probe() warn: argument 3 to %08lx specifier is cast from pointer
