hwrng: omap - Only fail if pm_runtime_get_sync returns < 0
commit ad8529fd 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. Fixes: 61dc0a44 ("hwrng: omap - Fix assumption that runtime_get_sync will always succeed") Signed-off-by:Dave Gerlach <d-gerlach@ti.com> Signed-off-by:
