Therefore the tps65910_rtc should be used on unregistering the rtc device. And device pointer should be retrieved from the platform_device structure. This patch fixes the below oops: Unable to handle kernel NULL pointer dereference at virtual address 00000008 Modules linked in: rtc_tps65910(-) CPU: 0 Not tainted (3.7.0-rc7-next-20121128-g6b1f974-dirty #7) PC is at tps65910_rtc_alarm_irq_enable+0x20/0x2c [rtc_tps65910] (tps65910_rtc_alarm_irq_enable+0x20/0x2c [rtc_tps65910]) (tps65910_rtc_remove+0x18/0x28 [rtc_tps65910]) (platform_drv_remove+0x18/0x1c) (__device_release_driver+0x70/0xcc) (driver_detach+0xb4/0xb8) (bus_remove_driver+0x7c/0xc0) (sys_delete_module+0x148/0x21c) Signed-off-by: Milo(Woogyom) Kim Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- Reading git-diff-tree failed
