Subject: [PATCH v2] ufs: core: Combine ufshcd_mq_poll_cqe functions
Date: Fri, 2 Jun 2023 06:50:48 +0800 [thread overview]
Message-ID: <20230601225048.12228-1-stanley.chu@mediatek.com> (raw)
Currently, ufshcd_mcq_poll_cqe_nolock() is only called by
ufshcd_mcq_poll_cqe_lock() with the addition of a spinlock wrapper
for ufshcd_mcq_poll_cqe_nolock(). Combining these two functions
into one would result in cleaner code.
