irqchip/mchp-eic: Fix error code in mchp_eic_domain_alloc()

2025-12-18T13:00:15+00:00

[ Upstream commit 7dbc0d40d8347bd9de55c904f59ea44bcc8dedb7 ] If irq_domain_translate_twocell() sets "hwirq" to >= MCHP_EIC_NIRQ (2) then it results in an out of bounds access. The code checks for invalid values, but doesn't set the error code. Return -EINVAL in that case, instead of returning success.

[ Upstream commit 0435bcc4e5858c632c1b6d5afa637580d9779890 ] The init callback must not decrement the reference count of the provided irqchip OF node.
