[PATCH 1/3] platform/x86: hp: hp_accel: Propagate errors from optional IRQ lookup

[phucduc . bui]

From: bui duc phuc <phucduc.bui@xxxxxxxxx>

platform_get_irq_optional() returns a positive IRQ number on success or
a negative error code on failure. For an optional IRQ, -ENXIO indicates
that no optional IRQ is available, while other errors should be propagated.

Propagate all error codes returned by platform_get_irq_optional() other
than -ENXIO.
