[ Upstream commit b8ada54fa1b83f3b6480d4cced71354301750153 ]
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") Cc: stable@vger.kernel.org # v5.19+
After a glance at the driver, the patch too seems safe to be applied to 5.10.y, despite I tried to limit it to 5.19.y and newer...
