Subject: [PATCH] blk-mq: remove blk_qc_t_to_tag and blk_qc_t_is_internal
Git-commit: efbabbe121f96d4b1a98a2c2ef5d2e8f7fb41c87
Patch-mainline: v5.16-rc1
References: jsc#PED-1183
Merge both functions into their only caller to keep the blk-mq tag to
blk_qc_t mapping as private as possible in blk-mq.c.
