Subject: [PATCH 5.4 08/14] perf/arm_pmu_platform: fix tests for platform_get_irq() failure
Date: Fri, 16 Sep 2022 12:08:15 +0200 [thread overview]
Message-ID: <20220916100443.542088404@linuxfoundation.org> (raw)
In-Reply-To: <20220916100443.123226979@linuxfoundation.org>
From: Yu Zhe <yuzhe@nfschina.com>
[ Upstream commit 6bb0d64c100091e131cd16710b62fda3319cd0af ]
The platform_get_irq() returns negative error codes. It can't actually
return zero.
