[Crosstoolchain-logs] [device-tree-compiler] 111/198: Make srcpos_{v, }error() more widely useful

[Hector Oron]

This is an automated email from the git hooks/post-receive script.

zumbi pushed a commit to branch upstream/1.4.x
in repository device-tree-compiler.

commit 0e2d3992258ff4129a8c0f79b660e92994411684
Author: David Gibson <david at gibson.dropbear.id.au>
Date:   Wed Jan 1 23:27:31 2014 +1100

    Make srcpos_{v,}error() more widely useful
    
    Allow them to take a prefix argument giving the general type of error,
    which will be useful in future.
