[ Upstream commit 32b378a9179ae4db61cfc5d502717214e6cd1e1c ]
Error code is overridden, in case the PLL doesn't lock. So, the USB initialization can continue. This leads to a platform freeze. This can be avoided by returning proper error code to avoid USB probe freezing the platform. It also displays proper errors in log.
