Attempt to build MUSB driver with CONFIG_PM=y (e.g. in the OTG mode) on DaVinci results in these link errors:
drivers/built-in.o: In function `musb_restore_context': led-triggers.c:(.text+0x714d8): undefined reference to `musb_platform_restore_context' drivers/built-in.o: In function `musb_save_context': led-triggers.c:(.text+0x71788): undefined reference to `musb_platform_save_context' This turned out to be caused by commit 9957dd97ec5e98dd334f87ade1d9a0b24d1f86eb (usb: musb: Fix compile error for omaps for musb_hdrc). Revert it, taking into account the rename of CONFIG_ARCH_OMAP34XX into CONFIG_ARCH_OMAP3 (which that commit fixed in a completely inappropriate way) and the recent addition of OMAP4 support.
