The IRQ work is added before the struct rtc is allocated and registered, but this struct is used in the IRQ handler. This may lead to a NULL pointer dereference. Switch to devm_rtc_allocate_device/rtc_register_device to allocate the rtc before calling menelaus_add_irq_work. Also, this solves a possible leak as the RTC is never released. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com> --- Lee, If that is ok with you, I would like to take this patch through the RTC tree. So I can have a follow up patch removing rtc_device_register(). Thanks drivers/mfd/menelaus.c | 13 +++++++++---- 1 file changed, 9 insertions(+), 4 deletions(-)
