ARM: OMAP: OTG integration: fix compiler warning
Tony reported the following compile warning after commit
eeb3711b89d68e147e05e7b43a49ecc5009dc157 ("ARM: OMAP2+: clean up some
cppcheck warnings"):
arch/arm/plat-omap/usb.c: In function 'omap_otg_init':
arch/arm/plat-omap/usb.c:40: warning: unused variable 'status'
This happens if CONFIG_ARCH_OMAP_OTG is set but
CONFIG_USB_GADGET_OMAP, CONFIG_USB_OHCI_HCD,
CONFIG_USB_OHCI_HCD_MODULE, and CONFIG_USB_OTG are all unset.
Fix by localizing the status variable to the blocks that use it.
Compile-tested only, with omap2plus_defconfig and omap2plus_defconfig
with CONFIG_USB_OHCI_HCD and CONFIG_USB_OTG enabled.
