X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=91cad911edd1612ed28f5cfb2d4c53a8824951a5;p=users%2Fhch%2Fmisc.git

scsi: ufs: host: mediatek: Fix unbalanced IRQ enable issue

Resolve the issue of unbalanced IRQ enablement by setting the
'is_mcq_intr_enabled' flag after the first successful IRQ enablement.
Ensure proper tracking of the IRQ state and prevent potential mismatches
in IRQ handling.
