qedi_dbg_do_not_recover_cmd_read() function invokes sprintf() directly\non a __user pointer, which results into the crash.\n\nTo fix this issue, use a small local stack buffer for sprintf() and then\ncall simple_read_from_buffer(), which in turns make the copy_to_user()\ncall.\n\nBUG: unable to handle page fault for address: 00007f4801111000\nPGD 8000000864df6067 P4D 8000000864df6067 PUD
