UBUNTU-CVE-2024-57978: Medium severity ubuntu/linux-hwe-edge vulnerability
In the Linux kernel, the following vulnerability has been resolved: media: imx-jpeg: Fix potential error pointer dereference in detachpm() The proble is on the first line: if (jpeg->pddev[i] && !pmruntimesuspended(jpeg->pddev[i])) If jpeg->pddev[i] is an error pointer, then passing it to pmruntimesuspended() will lead to an Oops. The other conditions check for both error pointers and NULL, but it would be more clear to use the ISERRORNULL() check for that.

In detach_pm(), use an IS_ERR_OR_NULL() check for jpeg->pd_dev[i] before calling pm_runtime_suspended(), so both error pointers and NULL values are skipped.
Linux kernel media: imx-jpeg detach_pm() pd_dev validation = IS_ERR_OR_NULL(jpeg->pd_dev[i])
