In the Linux kernel, the following vulnerability has been resolved:media: imx-jpeg: Fix potential error pointer dereference in detach_pm()The proble is on the first line:If jpeg->pd_dev[i] is an error pointer, then passing it to
pm_runtime_suspended() will lead to an Oops.  The other conditions
check for both error pointers and NULL, but it would be more clear to
use the IS_ERR_OR_NULL() check for that.
