Kuninori Morimoto b7a8d17db9 usb: gadget: renesas_usbhs: fixup section mismatch warning
Fix up the following section mismatch warnings:

WARNING: drivers/usb/renesas_usbhs/renesas_usbhs.o(.text+0xf5d): Section
mismatch in reference from the function usbhs_mod_probe() to the function
.devinit.text:usbhs_mod_host_probe() The function usbhs_mod_probe() references
the function __devinit usbhs_mod_host_probe().  This is often because
usbhs_mod_probe lacks a __devinit annotation or the annotation of
usbhs_mod_host_probe is wrong.

WARNING: drivers/usb/renesas_usbhs/renesas_usbhs.o(.text+0xfd7): Section
mismatch in reference from the function usbhs_mod_probe() to the function
.devexit.text:usbhs_mod_host_remove() The function usbhs_mod_probe() references
a function in an exit section.  Often the function usbhs_mod_host_remove() has
valid usage outside the exit section and the fix is to remove the __devexit
annotation of usbhs_mod_host_remove.

WARNING: drivers/usb/renesas_usbhs/renesas_usbhs.o(.text+0x1005): Section
mismatch in reference from the function usbhs_mod_remove() to the function
.devexit.text:usbhs_mod_host_remove() The function usbhs_mod_remove()
references a function in an exit section.  Often the function
usbhs_mod_host_remove() has valid usage outside the exit section and the fix is
to remove the __devexit annotation of usbhs_mod_host_remove.
