Subject: [PATCH] mmc: core: Fix tag set memory leak
Git-commit: 43d8dabb4074cf7f3b1404bfbaeba5aa6f3e5cfc
Patch-mainline: v5.2-rc1
References: bsc#1111666
The tag set is allocated in mmc_init_queue but never freed. This results
in a memory leak. This change makes sure we free the tag set when the
queue is also freed.
