Subject: [PATCH] scsi: ufs: core: Add NULL check in ufshcd_mcq_compl_pending_transfer()
Date: Sat, 12 Apr 2025 14:59:09 -0500 [thread overview]
Message-ID: <20250412195909.315418-1-chenyuan0y@gmail.com> (raw)
Add a NULL check for the returned hwq pointer by ufshcd_mcq_req_to_hwq().
This is similar to the fix in commit 74736103fb41
("scsi: ufs: core: Fix ufshcd_abort_one racing issue").
