Subject: mmc: sdhci-spear: fix deferred probing
From: Sergey Shtylyov <s.shtylyov@xxxxxx>
commit 8d0caeedcd05a721f3cc2537b0ea212ec4027307 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: 682798a596a6 ("mmc: sdhci-spear: Handle return value of platform_get_irq")
