Subject: usb: dwc2: fix default value for DMA support
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6118d0647b10eaca06b278dee2022602d8f2f07a;p=linux-beck.git

usb: dwc2: fix default value for DMA support

The current defaults for DMA results on a non-DMA platform in a unnecessary
error message:

  Invalid value 0 for param gadget-dma

So fix this by using dma_capable as default value.

Fixes: 9962b62f1be ("usb: dwc2: Deprecate g-use-dma binding")
