Subject: usb: dwc2: hcd: fix build warning
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3521a399dae8d66fc784cef70a78e65ce73e364f;p=linux-beck.git

usb: dwc2: hcd: fix build warning

commit db62b9a804b4 (usb: dwc2: host: don't
use dma_alloc_coherent with irqs disabled)
introduced a build warning by using NULL
as an integer. Fix that by just using 0 instead
of NULL.
