From: Cristian Ciocaltea <cristian.ciocaltea@collabora.com> stable inclusion from stable-v6.6.2 commit c6567bbfa558707696104fa3a051babfe821798f category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8IW7G Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit 5ad668a9ce83d819701fb7abc1c2236049ec15c2 ] 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().
