Subject: [PATCH] mmc: mvsdio: fix deferred probing
Git-commit: 8d84064da0d4672e74f984e8710f27881137472c
Patch-mainline: v6.4
References: git-fixes
The driver overrides the error codes returned by platform_get_irq() to
-ENXIO, 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.
Fixes: 9ec36cafe43b ("of/irq: do irq resolution in platform_get_irq")
