Subject: [PATCH v3 09/10] ufs: host: mediatek: Fix unbalanced IRQ enable issue
Date: Wed, 3 Sep 2025 10:44:45 +0800	[thread overview]
Message-ID: <20250903024631.496693-10-peter.wang@mediatek.com> (raw)
In-Reply-To: <20250903024631.496693-1-peter.wang@mediatek.com>

From: Peter Wang <peter.wang@mediatek.com>

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.
