From c1b034a4214e4ce81132be9db44e9fe3e2369351 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 29 Jul 2021 09:38:50 +0200 Subject: [PATCH] ALSA: usb-audio: Move tx_length quirk handling to quirk_flags There is another quirk for the transfer, and that's currently specific to Zoom R16/24, handled in create_standard_audio_quirk(). Let's move this also to the new quirk_flags.
