6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bart Van Assche <bvanassche@xxxxxxx>
[ Upstream commit ee36710912b2075c417100a8acc642c9c6496501 ]
Calling ufshcd_hba_exit() from a function that is called asynchronously
from ufshcd_init() is wrong because this triggers multiple race
conditions. Instead of calling ufshcd_hba_exit(), log an error message.
