An invalid memory access is observed in cros_ec_keyb_process()\nwhen receiving an EC_MKBP_EVENT_KEY_MATRIX event in cros_ec_keyb_work()\nin such case.\n\n Unable to handle kernel read from unreadable memory at virtual address 0000000000000028\n ...\n x3 : 0000000000000000 x2 : 0000000000000000\n x1 : 0000000000000000 x0 : 0000000000000000\n Call trace:\n input_event\n cros_ec_keyb_work\n blocking_notifier_call_chain\n ec_irq_thread\n\nIt's still unknown about why the kernel receives such malformed event,\nin any cases, the kernel shouldn't access `ckdev->idev` and friends if\nthe driver doesn't intend to initialize them."
