Subject: [PATCH 4.19 16/47] mmc: block: Make card_busy_detect() a bit more generic

From: Chaotian Jing <chaotian.jing@...iatek.com>

commit 3869468e0c4800af52bfe1e0b72b338dcdae2cfc upstream.

To prepare for more users of card_busy_detect(), let's drop the struct
request * as an in-parameter and convert to log the error message via
dev_err() instead of pr_err().
