According to drivers/input/misc/pcap_keys.c, the kernel module may sleep in the interrupt handler. The function call path is: pcap_keys_handler (interrupt handler) ezx_pcap_read mutex_lock --> may sleep
I do not find a good way to fix it, so I only report. This possible bug is found by my static analysis tool (DSAC) and checked by my code review.
Thanks, Jia-Ju Bai
