From 8422ad51652f8f33acd3f03f24ec2aea73083eb7 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Tue, 26 Feb 2019 12:20:26 -0700 Subject: [PATCH] kbuild: fix DTB .cmd source variable *.dts are processed using a custom command, then the C pre-processor is run on them, then they are compiled using dtc. Thus, the dependency files generated by both cpp and dtc reference a temporary file name rather than the actual source file. While this information isn't used for any purpose by the build system, and hence this causes no functional issue, it does cause the dependency files to contain invalid and confusing data, which is unhelpful while debugging build problems. Fix this using sed.
