Subject: [PATCH v2 3/3] ufs: core: Remove max_num_rtt field from ufs_hba_variant_ops
Date: Fri, 12 Jun 2026 07:26:32 +0800	[thread overview]
Message-ID: <20260611232632.2324422-4-ed.tsai@mediatek.com> (raw)
In-Reply-To: <20260611232632.2324422-1-ed.tsai@mediatek.com>

From: Ed Tsai <ed.tsai@mediatek.com>

Remove the max_num_rtt field from ufs_hba_variant_ops as it has been
replaced by the get_hba_nortt() callback which provides more flexible
platform-specific RTT capability handling.
