Subject: kernel-module-split.bbclass: support muti-lines in module conf
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=33a8d89757ea50636fdf784883df604235e540d7;p=thirdparty%2Fopenembedded%2Fopenembedded-core.git

kernel-module-split.bbclass: support muti-lines in module conf

The expanded bitbake variables are raw strings so it does not support
writting multiple lines to a kernel module conf, add the support by
decoding it with 'unicode-escape'.
