This change is causing a kernel panic when powering down the pads on entering suspend with the Jetson TX2 platform. The panic occurs because the 'xudc->curr_utmi_phy' is not configured on this platform and we do not check to see if the pointer is valid before attempting to deference the pointer. Fix this by checking to see if the 'phy' pointer passed to tegra_phy_xusb_utmi_pad_power_on/down is valid.Applied, thanks
We need this fix for Linux v6.1. The crash is still seen as of v6.1-rc3. Thanks Jon -- nvpublic
