From c9f36f04a8a2725172cdf2b5e32363e4addcb14c Mon Sep 17 00:00:00 2001 From: Seunghwan Baek sh8267.baek@samsung.com Date: Wed, 10 Dec 2025 15:38:54 +0900 Subject: [PATCH] scsi: ufs: core: Add ufshcd_update_evt_hist() for UFS suspend error

If UFS resume fails, the event history is updated in ufshcd_resume(), but there is no code anywhere to record UFS suspend. Therefore, add code to record UFS suspend error event history.
