Subject: [PATCH] ALSA: atmel: ac97c: fix error return code in atmel_ac97c_probe()
Date: Fri, 30 Jun 2017 17:34:23 -0500	[thread overview]
Message-ID: <20170630223423.GA20635@embeddedgus> (raw)

platform_get_irq() returns an error code, but the ac97c
driver ignores it and always returns -ENXIO. This is not correct,
and prevents -EPROBE_DEFER from being propagated properly.
Notice that platform_get_irq() no longer returns 0 on error.

Print and propagate the return value of platform_get_irq on failure.
