[PATCH] usb: musb: - kill the compile warning
From: Bryan Wu
Date: Fri Feb 06 2009 - 05:21:46 EST
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.
