So, I apply Tixy's patch on lsk-v3.10 branch of lsk. and tested
compilation. That's fine.
Is there some way to let me push the change to lsk. or let me put the
change on a git.linaro.org and then You pull my tree for this change?
Either works, though you should apply the patch on one of the topic branches then merge that into the LSK branches - probably the warnings branch is best here.
Please push to linux-linaro-lsk and linux-linaro-lsk-android - those are currently the master branches. The changes on linux-linaro-lsk should be merged into the -android branch.
