Subject: [PATCH] rtc: mxc_v2: fix wake IRQ leak on probe failure and remove()
Date: Fri, 18 Sep 2026 22:54:29 +0700 [thread overview]
Message-ID: <20260918155429.2549137-1-congnt264@gmail.com> (raw)
dev_pm_set_wake_irq() in probe has no matching dev_pm_clear_wake_irq()
anywhere -- not on later probe-failure paths, not in remove(). Switch
to devm_pm_set_wake_irq(), which registers the clear automatically on
every exit path.
Fixes: fbc5ee9a6955 ("rtc: mxc_v2: use dev_pm_set_wake_irq() to simplify code")
