[PATCH 6.3 118/199] mmc: owl: fix deferred probing

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Sergey Shtylyov <s.shtylyov@xxxxxx>

[ Upstream commit 3c482e1e830d79b9be8afb900a965135c01f7893 ]

The driver overrides the error codes 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.

Fixes: ff65ffe46d28 ("mmc: Add Actions Semi Owl SoCs SD/MMC driver")
