Subject[PATCH] mmc: sh_mmcif: Use platform_get_irq_optional() for optional interrupt
Date
As platform_get_irq() now prints an error when the interrupt does not
exist, a scary warning may be printed for an optional interrupt:

sh_mmcif ee200000.mmc: IRQ index 1 not found

Fix this by calling platform_get_irq_optional() instead for the second
interrupt, which is optional.

Remove the now superfluous error printing for the first interrupt, which
is mandatory.

Fixes: 7723f4c5ecdb8d83 ("driver core: platform: Add an error message to platform_get_irq*()")
