[PATCH 1/2] EDAC/aspeed: Fix handling of platform_get_irq() error
From: Krzysztof Kozlowski <krzk@kernel.org>
Date: 2020-08-27 07:07:55
Also in:
linux-aspeed, linux-edac, lkml
Subsystem:
edac-ast2500, edac-core, the rest · Maintainers:
Stefan Schaeckeler, Borislav Petkov, Tony Luck, Linus Torvalds
platform_get_irq() returns -ERRNO on error. In such case comparison
to 0 would pass the check.
Fixes: 9b7e6242ee4e ("EDAC, aspeed: Add an Aspeed AST2500 EDAC driver")
