Subject: [PATCH] irqchip/loongson-liointc: Fix an error handling path in liointc_init()
Date: Mon,  1 Aug 2022 21:28:07 +0200	[thread overview]
Message-ID: <1a6d74ab70712279023aa7bdbd31bd3aec103bc0.1659382063.git.christophe.jaillet@wanadoo.fr> (raw)

All errors lead to the error handling path, except this one.
Fix it and release some resources before returning if this test fails.

Fixes: 0858ed035a85 ("irqchip/loongson-liointc: Add ACPI init support")
