From 01517654bc258efb2610e53e99fa4ef641d134b9 Mon Sep 17 00:00:00 2001 From: Peter Wang Date: Tue, 10 Feb 2026 14:41:43 +0800 Subject: [PATCH] scsi: ufs: core: Add debug log for UIC command timeout It is difficult to debug when a UIC command timeout occurs simultaneously with a UIC command complete interrupt. Currently, we only see the timeout log without any debug information, making it unclear whether the UFS device failed to respond or the host entered an incorrect state. Add a one-line log to cover this situation.
