This will get initially pushed out as testing and the branch will get rebased onto Greg KH's staging-next branch sometime soon. However, I think there are some other places the BIT macro can be correctly used in this driver if you are willing to take it further. Note that you can only do these by checking the datasheet to be sure we aren't writing part of a large field in the register! In the status register the bottom for bits are single bit fields. #define AD7746_STATUS_EXCERR (1 << 3) #define AD7746_STATUS_RDY (1 << 2) #define AD7746_STATUS_RDYVT (1 << 1) #define AD7746_STATUS_RDYCAP (1 << 0) As are the cap setup register bits #define AD7746_CAPSETUP_CAPEN (1 << 7) #define AD7746_CAPSETUP_CIN2 (1 << 6) /* AD7746 only */ #define AD7746_CAPSETUP_CAPDIFF (1 << 5) #define AD7746_CAPSETUP_CACHOP (1 << 0) Some of the vt setup register are also single bits but as that register is a more complex mess and some other bits are hard to define macros for perhaps leave it alone. It's another one arguing in favour of a ZERO(bit) macro but I fear persuading people of that will be an uphill struggle :( Anyhow the two registers mentioned above are a clear cut as the one you've done so perhaps tidy those up as well?
