Subject: usb: musb: USB_TI_CPPI41_DMA requires dmaengine support

From: Arnd Bergmann <[email protected]>

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.
