Reduced checkpatch errors from 185 to 2, and warnings from 4 to 1 in
sound/usb/quirks-table.h.

Remaining issues were reviewed and considered non-blocking.

Honestly speaking, I don't find it's much improvement from the code
readability POV.  (And you don't have to "correct" the spaces in
comment lines :)

That is, if the reason of the changes is only about the complaint from
checkpatch, we can simply ignore it.  Above all, applying space-only
fixes would make the stable backports more difficult.

OTOH, if we really want to improve the code readability, maybe it'd be
better to introduce some macros to simplify the definitions.  e.g.

/* Quirk driver_info, use like QUIRK_DRIVER_INFO { ... } */
#define QUIRK_DRIVER_INFO \
	.driver_info = (unsigned long)&(const struct snd_usb_audio_quirk)

/* Quirk data entry for struct audioformat */
#define QUIRK_DATA_AUDIOFORMAT \
	.data = &(const struct audioformat)
/* Quirk data entry for struct snd_usb_midiendpoint_info */
#define QUIRK_DATA_MIDI_EP_INFO \
	.data = &(const struct snd_usb_midi_endpoint_info)

and replace accordingly.

But again, I'm not sure whether it's worth.  Macros might be good from
the code safety as the open code is error prone, though.


thanks,

Takashi

FWIW, the patches below are what I had in my mind.

Right. Your patchset makes way more sense when you read the codebase.
As you already made the code better, I dropped the patch for the
"cleanup" and, left only the support for Yamaha P-125 patch.
