Summary
serial: 8250: omap: Don't skip resource freeing if pm_runtime_resume_and_get() failed
Details

In the Linux kernel, the following vulnerability has been resolved:

serial: 8250: omap: Don't skip resource freeing if pmruntimeresumeandget() failed

Returning an error code from .remove() makes the driver core emit the little helpful error message:

remove callback returned a non-zero value. This will be ignored.

and then remove the device anyhow. So all resources that were not freed are leaked in this case. Skipping serial8250unregisterport() has the potential to keep enough of the UART around to trigger a use-after-free.

So replace the error return (and with it the little helpful error message) by a more useful error message and continue to cleanup.
