Subject: usb/phy: fix PPC64 build errors in phy-fsl-usb.c

From: Randy Dunlap <[email protected]>

[ Upstream commit a39ba90a1cc7010edb0a7132e1b67f3d80b994e9 ]

Fix build errors when built for PPC64:
These variables are only used on PPC32 so they don't need to be initialized for PPC64.

../drivers/usb/phy/phy-fsl-usb.c: In function 'usb_otg_start':

and the sysfs "show" function return type should be ssize_t, not int:

../drivers/usb/phy/phy-fsl-usb.c:1042:49: error: initialization of 'ssize_t (*)(struct device *, struct device_attribute *, char *)' {aka 'long int (*)(struct device *, struct device_attribute *, char *)'} from incompatible pointer type 'int (*)(struct device *, struct device_attribute *, char *)' [-Werror=incompatible-pointer-types]
static DEVICE_ATTR(fsl_usb2_otg_state, S_IRUGO, show_fsl_usb2_otg_state, NULL);
