ALSA: hda: Add helper macros for DSP capable devices
Browse files Browse the repository at this point in the history
HDAudio drivers make heavy use of I/O operations. Declare a range of
update, read and write helpers similar to those available for HDAudio
legacy driver. These macros are used by AVS driver to improve code
readability.
