Subject: [PATCH v2 2/2] ufs: mcq: Convert MCQ_CFG_n to a inline function
Date: Mon, 20 May 2024 07:14:57 +0900 [thread overview]
Message-ID: <20240519221457.772346-3-minwoo.im@samsung.com> (raw)
In-Reply-To: <20240519221457.772346-1-minwoo.im@samsung.com>
Unlike the previous patch, this patch does not fix any issues, but,
inline functions are much more preferred over macros, so this patch
converted MCQ_CFG_n macro in ufs-mcq to an inline function along with
the previous patch.
