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
