Subject: For separate kernel source and build directories, allow the kernel build
X-Git-Url: http://git.tremily.us/gitweb.cgi?a=commitdiff_plain;h=283af72cd819c32f7fe6a182f06fecb7dfa00bb8;p=comedi.git

For separate kernel source and build directories, allow the kernel build
directory's Makefile to specify KERNELSRC using a relative path.
This avoids having to use the --with-kernelsrcdir option when configuring
Comedi for SuSE Linux's kernels.
