## Overview

In the Linux kernel, the following vulnerability has been resolved:

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

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.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
