ALSA: hda - convert to hda_device_id
Finally we have a proper infrastructure to generate the modaliases automatically, let's move to hda_device_id from the legacy hda_codec_preset that contains basically the same information. The patch function hook is stored in driver_data field, which is long, and we need an explicit cast. Other than that, the conversion is mostly straightforward. Each entry is even simplified using a macro, and the lengthy (and error-prone) manual modaliases got removed. As a result, we achieved a quite good diet: 14 files changed, 407 insertions(+), 595 deletions(-) Reviewed-by: Vinod Koul <vinod.koul@intel.com> Tested-by: Subhransu S Prusty <subhransu.s.prusty@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
