Subject[PATCH] spi: rspi: Use platform_get_irq_byname_optional() for optional irqs
Date
As platform_get_irq_byname() now prints an error when the interrupt
does not exist, scary warnings may be printed for optional interrupts:

renesas_spi e6b10000.spi: IRQ rx not found
renesas_spi e6b10000.spi: IRQ mux not found

Fix this by calling platform_get_irq_byname_optional() instead.
Remove the no longer needed printing of platform_get_irq errors, as the
remaining calls to platform_get_irq() and platform_get_irq_byname() take
care of that.

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

This is a fix for v5.4.
