From ee36710912b2075c417100a8acc642c9c6496501 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Mon, 18 Dec 2023 14:52:15 -0800 Subject: scsi: ufs: core: Remove the ufshcd_hba_exit() call from ufshcd_async_scan() 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.
