The driver may sleep under a spinlock. The function call path is: tsi148_master_write \ tsi148_master_read (acquire the spinlock) vme_register_error_handler kmalloc(GFP_KERNEL) --> may sleep To fix it, GFP_KERNEL is replaced with GFP_ATOMIC. This bug is found by my static analysis tool(DSAC) and checked by my code review. Signed-off-by: Jia-Ju Bai <baijiaju1990@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |
