X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b5a6a4e5baeff6a20a5c5e8711d8b08658efacbb;p=openwrt%2Fstaging%2Fblogic.git

usb: gadget: amd5536udc: Replace PCI pool old API

The PCI pool API is deprecated. This commit replaces the PCI pool old
API by the appropriate function with the DMA pool API.
