Subject: kernel: modules: usb: Add DWC3 Qualcomm kmod
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=c9f6116fd007ee360cbabf12ba830e3f381cee18;p=openwrt%2Fstaging%2Faparcar.git

kernel: modules: usb: Add DWC3 Qualcomm kmod

Since kernel 4.18 support for Qualcomm glue layer was
moved from DWC3 OF Simple to a separate DWC3 QCOM module.
So lets add it and make it depend on 4.19 kernel and make
sure that DWC3 OF Simple is not included if 4.19 is used.
