According to drivers/scsi/wd719x.c, the kernel module may sleep under a spinlock. The function call path is: wd719x_host_reset (acquire the spinlock) wd719x_chip_init request_firmware --> 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
