SubjectRE: [PATCH v2] ufs: core: Combine ufshcd_mq_poll_cqe functions
From
Date
>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.
