我试图将Linux内核版本从4.4.14（trunk）降级到3.18.44。
我对目标Linux系统ipq806x进行了必要的makefile更改。
但是在构建时，我收到补丁失败错误。下面给出了构建日志代码段。有谁遇到过这样的错误。请分享您的评论。
pplying patch platform/301-ARM-qcom-add-Netgear-Nighthawk-X4-R7500-device-tree.patch
patching file arch/arm/boot/dts/Makefile
The next patch would create the file arch/arm/boot/dts/qcom-ipq8064-r7500.dts,
which already exists! Applying it anyway.

最佳答案
从日志中清除后，由于dts修补失败，编译失败。
如果不需要失败的补丁文件，请在删除后尝试编译。
