Subject: base-files: quote values when evaluating uevent
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=da52dd0c83;p=openwrt%2Fstaging%2Flinusw.git

base-files: quote values when evaluating uevent

When sourcing /sys/class/block/*/uevent values have to be quoted as
they may contain spaces (e.g. in PARTNAME).
Fix this by pre-processing with sed before sourcing.
