[ Upstream commit d41ce98a122c13ea77938af04ef06fb12ae0c69e ] With randconfig build testing on arm64, we can run into a configuration that has CONFIG_OMAP_CONTROL_PHY=m and CONFIG_OMAP_USB2=y, which in turn causes a link failure: drivers/phy/ti/phy-omap-usb2.o: In function `omap_usb_phy_power': phy-omap-usb2.c:(.text+0x17c): undefined reference to `omap_control_phy_power' I could not come up with a good way to correctly describe the relation of the two symbols, but if we just select CONFIG_OMAP_CONTROL_PHY during compile testing, we can no longer run into the broken configuration.
