[PATCH RFC 10/13] mmc: sdhci-spear: fix deferred probing
From: Sergey Shtylyov <hidden>
Date: 2021-12-23 17:12:17
Subsystem:
multimedia card (mmc), secure digital (sd) and sdio subsystem, secure digital host controller interface (sdhci) driver, secure digital host controller interface (sdhci) st spear driver, the rest · Maintainers:
Ulf Hansson, Adrian Hunter, Viresh Kumar, Linus Torvalds
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. IRQ0 is no longer returned by platform_get_irq(), so we now
can safely ignore it...
Fixes: 682798a596a6 ("mmc: sdhci-spear: Handle return value of platform_get_irq")
