Subject: ASoC: fsl_ssi: Fix platform_get_irq() error handling
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=28ecc0b658e2ac882faa80e7ff1d72d144299bd0;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

ASoC: fsl_ssi: Fix platform_get_irq() error handling

We should check whether platform_get_irq() returns a negative number and
propagate the error in this case.
