Subject: scripts: gen-dependencies.sh: fix kmod dependency generation
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=2e5411518fa6a5bed67aa9ea7e8ca87b273ab509;p=openwrt%2Fstaging%2Fyousong.git

scripts: gen-dependencies.sh: fix kmod dependency generation

Do not output faulty ".ko" dependency if a scanned .ko file has an empty
"depends=" specification, also replace the `grep | sed | awk` chain with a
single sed program.
