[PATCH 0/2] Renesas: propagate platform_get_irq() error upstream

[Sergei Shtylyov]

Hello.

   Here's 2 patches against DaveM's 'net.git' repo. We fix error handling for
platform_get_irq() that overrides the error code with -ENODEV which e.g.
prevents the deferred probing from working.

[1/2] ravb: propagate platform_get_irq() error upstream
[2/2] sh_eth: propagate platform_get_irq() error upstream

MBR, Sergei

[PATCH 1/2] ravb: propagate platform_get_irq() error upstream

[Sergei Shtylyov]

The driver overrides the error returned by platform_get_irq() with -ENODEV
which e.g. precludes the deferred  probing from working. Propagate the real
error code to the driver core instead.
