Dan CarpenterandGreg Kroah-Hartman 1b2af918bb media: imx-jpeg: Fix potential error pointer dereference in detach_pm() ...

commit 1378ffec30 upstream.

The proble is on the first line:

	if (jpeg->pd_dev[i] && !pm_runtime_suspended(jpeg->pd_dev[i]))

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.
