Subject: treewide: replace local mkdir_p implementations
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7f12c89d0b99a2f04e91b2327e74c049f6362b67;p=project%2Fprocd.git

treewide: replace local mkdir_p implementations

Replace local implementations of mkdir_p in favour of using the
more robust implementation now added to libubox.
