Subject: scripts: generate_rust_analyzer: Handle sub-modules with no Makefile
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5c7548d5a25306dcdb97689479be81cacc8ce596;p=linux.git

scripts: generate_rust_analyzer: Handle sub-modules with no Makefile

More complex drivers might want to use modules to organize their Rust
code, but those module folders do not need a Makefile.
generate_rust_analyzer.py currently crashes on those. Fix it so that a
missing Makefile is silently ignored.
