4.2.8-ckt2 -stable review patch.  If anyone has any objections, please let me know.

From: Arnd Bergmann <arnd@arndb.de>

commit 183e53e8ddf4165c3763181682189362d6b403f7 upstream.

The CPPI-4.1 driver selects TI_CPPI41, which is a dmaengine
driver and that may not be available when CONFIG_DMADEVICES
is not set:

warning: (USB_TI_CPPI41_DMA) selects TI_CPPI41 which has unmet direct dependencies (DMADEVICES && ARCH_OMAP)

This adds an extra dependency to avoid generating warnings in randconfig
builds. Ideally we'd remove the 'select' statement, but that has the
potential to break defconfig files.
