#1679112 — [PATCH v2] ALSA: x86: fix error return code in hdmi_lpe_audio_probe()

Subject[PATCH v2] ALSA: x86: fix error return code in hdmi_lpe_audio_probe()
Message-ID<tYayt-1z6-7@gated-at.bofh.it>
platform_get_irq() returns an error code, but the intel_hdmi_audio
driver ignores it and always returns -ENODEV. This is not correct,
and prevents -EPROBE_DEFER from being propagated properly. Also,
notice that platform_get_irq() no longer returns 0 on error.

Print error message and propagate the return value of platform_get_irq
on failure.

There is no change by your patch in this regard, right?

You are correct. I just pointing it out. This is the commit that  
changed the platform_get_irq code:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e330b9a6bb35dc7097a4f02cb1ae7b6f96df92af
