Subject: [PATCH v4 12/29] ufs: core: Change the type of one ufshcd_send_command() argument
Date: Fri, 12 Sep 2025 11:21:33 -0700	[thread overview]
Message-ID: <20250912182340.3487688-13-bvanassche@acm.org> (raw)
In-Reply-To: <20250912182340.3487688-1-bvanassche@acm.org>

Change the 'task_tag' argument into an LRB pointer. This patch prepares
for the removal of the hba->lrb[] array.
