Subject: [PATCH 02/11] USB: musb: kill compile warning for Blackfin systems

From: Bryan Wu <cooloney@...nel.org>

The Blackfin version of musb_read_target_reg_base() returns a u16 when the
common code expects a (void __iomem *), so update the Blackfin function to
return the right value.  This fixes the compile warning:

drivers/usb/musb/musb_core.c: In function 'musb_core_init':
drivers/usb/musb/musb_core.c:1448: warning: assignment makes pointer from
	integer without a cast
