usb: dwc2: fixes host_dma logic
Browse files Browse the repository at this point in the history
This patch moves the the host_dma initialization
before dwc2_set_param_dma_desc_enable() and
dwc2_set_param_dma_desc_fs_enable(). The reason being
that both function need it.

Fixes: 1205489cee75bf39 ("usb: dwc2: Get host DMA device properties")
