Subject: [PATCH] scsi: ufs: ufshpb: Do not report victim error in HCM
Git-commit: 10163cee1f06fc2e17bcf7bbc2982337202d1d5c
Patch-mainline: v5.15-rc1
References: jsc#PED-818

In host control mode, eviction is perceived as an extreme measure. There
are several conditions that both the entering and exiting regions should
meet, so that eviction will take place.

The common case however, is that those conditions are rarely met, so it is
normal that the act of eviction fails.  Therefore, do not report an error
in host control mode if eviction fails.
