[ Upstream commit 71150ac12558bcd9d75e6e24cf7c872c2efd80f3 ]
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: 660fc733bd74 ("mmc: bcm2835: Add new driver for the sdhost controller.") Cc: stable@vger.kernel.org # v5.19+
After a glance at the driver, the patch seems safe to be applied to 5.15.y, despite I tried to limit it to 5.19.y and newer...
