usb: gadget: udc: amd5536 depends on HAS_DMA
[ Upstream commit 8097cf2fb3b2205257f1c76f4808e3398d66b6d9 ]
USB_AMD5536UDC should depend on HAS_DMA since it selects USB_SNP_CORE,
which depends on HAS_DMA and since 'select' does not follow any
dependency chains.
Fixes this kconfig warning:
WARNING: unmet direct dependencies detected for USB_SNP_CORE
Depends on [n]: USB_SUPPORT [=y] && USB_GADGET [=y] && (USB_AMD5536UDC [=y] || USB_SNP_UDC_PLAT [=n]) && HAS_DMA [=n]
Selected by [y]:
- USB_AMD5536UDC [=y] && USB_SUPPORT [=y] && USB_GADGET [=y] && USB_PCI [=y]
