Subject: ASoC: stm32: i2s: return the get_irq error
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=0bbf4084e0cfbbbff8673f3b9867778d5d4b1d6f;p=openwrt%2Fstaging%2Fblogic.git

ASoC: stm32: i2s: return the get_irq error

During probe, return the "get_irq" error value instead of -ENOENT. This
allows the driver to be deferred probed if needed.
