Subject: usb: dwc2: gadget: fix default value for gadget-dma-desc
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=efc95b2ca42424de222119a3a260624f3a050f8e;p=linux-beck.git

usb: dwc2: gadget: fix default value for gadget-dma-desc

The current default for gadget DMA descriptor results on bcm2835 in a
unnecessary error message:

  Invalid value 1 for param gadget-dma-desc

So fix this by using hw->dma_desc_enable as default value.
