Subject: [PATCH v4 20/29] ufs: core: Use hba->reserved_slot
Date: Fri, 12 Sep 2025 11:21:41 -0700	[thread overview]
Message-ID: <20250912182340.3487688-21-bvanassche@acm.org> (raw)
In-Reply-To: <20250912182340.3487688-1-bvanassche@acm.org>

Use hba->reserved_slot instead of open-coding it. This patch prepares
for changing the value of hba->reserved_slot.
