This is the definition of the UFS_BIT() macro I found in drivers/scsi/ufs/ufshci.h: #define UFS_BIT(x) (1L << (x)) Using this macro makes code longer instead of shorter and does not improve code readability. Is this macro really useful? Wouldn't it be better to remove the UFS_BIT() macro instead of introducing more uses of it? Thanks, Bart.
