Subject: usr: sanitize deps_initramfs list
|
|
|
|
|
|
|
|
|
|
If any filename in the intramfs dependency
|
|
|
|
|
list contains a colon, that causes a kernel
|
|
|
|
|
build error like this:
|
|
|
|
|
|
|
|
|
|
/devel/openwrt/build_dir/linux-ar71xx_generic/linux-3.6.6/usr/Makefile:58: *** multiple target patterns. Stop.
|
|
|
|
|
make[5]: *** [usr] Error 2
|
|
|
|
|
|
|
|
|
|
Fix it by removing such filenames from the
|
|
|
|
|
deps_initramfs list.
