From: Cristian Ciocaltea Date: Thu, 7 Sep 2023 17:10:02 +0000 (+0300) Subject: ASoC: cs35l41: Initialize completion object before requesting IRQ X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5ad668a9ce83d819701fb7abc1c2236049ec15c2;p=linux.git ASoC: cs35l41: Initialize completion object before requesting IRQ Technically, an interrupt handler can be called before probe() finishes its execution, hence ensure the pll_lock completion object is always initialized before being accessed in cs35l41_irq().
