Subject: [PATCH 6/6] usb: musb: - kill the compile warning

drivers/usb/musb/musb_core.c:1433: warning: assignment makes pointer
from integer without a cast
	hw_ep->target_regs = musb_read_target_reg_base(i, mbase);

static inline u16 musb_read_target_reg_base(u8 i, void __iomem *mbase);

this is a common bug, but a bug still ?  mbase is a 32/64 bit pointer,
but we return a u16 to assign to a pointer ?  seems odd :)

So return right pointer in the stub.
