Hello, I updated the patches to consider the request to split patch #3 (c.f. https://mailman.alsa-project.org/pipermail/alsa-devel/2021-March/181275.html ). The patch #3 now only contains changes related to DJM-850 support as the fix it was previously containing was applied in linux 5.12 (c.f. https://mailman.alsa-project.org/pipermail/alsa-devel/2021-March/181279.html ). The patches should be ready to merge into linux 5.13 . Thank you :) Patches list : [PATCH v2 1/4] ALSA: usb-audio: Add Pioneer DJM-850 to quirks-table [PATCH v2 2/4] ASLA: usb-audio: Declare Pioneer DJM-850 mixer [PATCH v2 3/4] ALSA: usb-audio: Configure Pioneer DJM-850 samplerate [PATCH v2 4/4] ASLA: usb-audio: fix Pioneer DJM-850 control label
