If anyone has any objections, please let me know. ------------------ From: Bart Van Assche [ Upstream commit dd4299af9b049c0dcb28699327ebc1386aab4b2a ] Since 'tag' is only used inside the if-statement, move the 'tag' assignment into the if-statement. This patch prepares for introducing a WARN_ON_ONCE() call in ufshcd_mcq_get_tag() if the tag lookup fails.
