Subject: [PATCH v2 23/30] ufs: core: Use hba->reserved_slot
Date: Mon, 11 Aug 2025 10:34:35 -0700	[thread overview]
Message-ID: <20250811173634.514041-24-bvanassche@acm.org> (raw)
In-Reply-To: <20250811173634.514041-1-bvanassche@acm.org>

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