Subject: [PATCH AUTOSEL 5.15 19/21] perf/arm_pmu_platform: fix tests for platform_get_irq() failure
Date: Sat, 10 Sep 2022 17:17:50 -0400 [thread overview]

In-Reply-To: <20220910211752.70291-1-sashal@kernel.org>
From: Yu Zhe <yuzhe@nfschina.com>
[ Upstream commit 6bb0d64c100091e131cd16710b62fda3319cd0af ]
