Subject: [PATCH 5.15 134/136] scsi: ufs: core: Enable link lost interrupt

From: Kiwoong Kim <kwmad.kim@...sung.com>

commit 6d17a112e9a63ff6a5edffd1676b99e0ffbcd269 upstream.

Link lost is treated as fatal error with commit c99b9b230149 ("scsi: ufs:
Treat link loss as fatal error"), but the event isn't registered as
interrupt source. Enable it.
