From: Takashi Iwai Date: Mon, 28 Oct 2019 13:06:34 +0000 (+0100) Subject: ALSA: hda: Allow non-Intel device probe gracefully X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=91636a82044a2821201b54faac4d1d2425260842;p=linux.git ALSA: hda: Allow non-Intel device probe gracefully The recent addition of snd_intel_dsp_driver_probe() check caused a spurious kernel warning when the driver is loaded for a non-Intel hardware due to snd_BUG_ON(). Moreover, for such a hardware, we should always return SND_INTEL_DSP_DRIVER_ANY, not check the dsp_driver option at all. This patch fixes these issues for non-Intel devices.
