According to drivers/usb/host/isp116x-hcd.c, the kernel module may sleep under a spinlock. The function call path is: isp116x_start (acquire the spinlock) device_init_wakeup device_wakeup_enable wakeup_source_register wakeup_source_create kmalloc(GFP_KERNEL) --> 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
