Subject: [PATCH v2 1/2] mmc: core: change __mmc_poll_for_busy() parameter type
Date: Thu,  4 Nov 2021 15:32:30 +0900	[thread overview]
Message-ID: <20211104063231.2115-2-huijin.park@samsung.com> (raw)
In-Reply-To: <20211104063231.2115-1-huijin.park@samsung.com>

This patch changes the __mmc_poll_for_busy() first parameter type
from 'struct mmc_card*' to 'struct mmc_host*'.
Because the function refers only 'struct mmc_host' to get hostname.
