From c616696a902987352426fdaeec1b0b3240949e6b Mon Sep 17 00:00:00 2001 From: Adrian Hunter adrian.hunter@intel.com Date: Fri, 3 Nov 2023 10:47:17 +0200 Subject: [PATCH] mmc: block: Be sure to wait while busy in CQE error recovery
STOP command does not guarantee to wait while busy, but subsequent command MMC_CMDQ_TASK_MGMT to discard the queue will fail if the card is busy, so be sure to wait by employing mmc_poll_for_busy().
