Subject: hwrng: omap - Only fail if pm_runtime_get_sync returns < 0

From: Dave Gerlach <[email protected]>

commit ad8529fde9e3601180a839867a8ab041109aebb5 upstream.

Currently omap-rng checks the return value of pm_runtime_get_sync and reports failure if anything is returned, however it should be checking if ret < 0 as pm_runtime_get_sync return 0 on success but also can return 1 if the device was already active which is not a failure case. Only values < 0 are actual failures.
