[PATCH v2 0/2] ALSA: usb-audio: presonus s1810 minor cleanup and document

From: fenugrec via B4 Relay

patch v2 : apologies, I had missed an __le32 field.

- Use __le32 fields for structures sent/received over USB
Addresses a comment from when this driver was initially merged:
https://lore.kernel.org/all/s5hd0agcjw1.wl-tiwai@xxxxxxx/

- Document constants and protocol details common to the Studio 1810 and
1824c devices

Except for a hypothetical big-endian platform (which I cannot test) where the first
commit would make a difference, both these should have no functional
change.
