Subject: net: smc91x: propagate irq return code
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bd59cfc51df7ddc88755a60a1293cee55f5d0a12;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

net: smc91x: propagate irq return code

The smc91x driver doesn't honor the probe deferral mechanism when the
interrupt source is not yet available, such as one provided by a gpio
controller not probed.

Fix this by propagating the platform_get_irq() error code as the probe
return value.
