Subject: [PATCH] mmc: omap_hsmmc: fix deferred probing
Git-commit: fb51b74a57859b707c3e8055ed0c25a7ca4f6a29
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")
