[PATCH v2] ALSA: usb-audio: Add quirk for PreSonus AudioBox USB
From: Abhinav Mahadevan
Date: Mon Apr 27 2026 - 21:00:27 EST
The PreSonus AudioBox USB (0x194f:0x0301) only supports S24_3LE
format for both playback and capture. It does not support S16_LE
despite being a USB full-speed device. Add explicit format quirks
for both the playback (interface 2) and capture (interface 3)
interfaces to ensure correct format negotiation.

v2: Fix placement - entry was incorrectly inside a #if 0 disabled block.
Moved to after the #endif /* disabled */.
