commit b8ada54fa1b83f3b6480d4cced71354301750153 upstream.
The driver overrides the error codes and IRQ0 returned by platform_get_irq()
to -EINVAL, so if it returns -EPROBE_DEFER, the driver will fail the probe
permanently instead of the deferred probing. Switch to propagating the error
codes upstream. Since commit ce753ad1549c ("platform: finally disallow IRQ0
in platform_get_irq() and its ilk") IRQ0 is no longer returned by those APIs,
so we now can safely ignore it...
Fixes: cbcaac6d7dd2 ("mmc: meson-gx-mmc: Fix platform_get_irq's error checking")
