Olivia Mackintosh has posted to alsa-devel reporting that there's a potential bug that could break mixer quirks for Pioneer devices introduced by 6d27788160362a7ee6c0d317636fe4b1ddbe59a7 "ALSA: usb-audio: Add support for the Pioneer DJM 750MK2 Mixer/Soundcard".
This happened because the DJM 750 MK2 was added last to the Pioneer DJM device table index and defined as 0x4 but was added to snd_djm_devices[] just after the DJM 750 (MK1) entry instead of last, after the DJM 900 NXS2. This escaped review.
Let's reorder the entries in snd_djm_devices[] so they match the Pioneer DJM device table index #define's.
