When you do this, please align continuations at the appropriate
open parenthesis using maximal initial tabs and minimal spaces
for alignment.

		if (size != sizeof(struct binder_version) ||
		    put_user(BINDER_CURRENT_PROTOCOL_VERSION,
			     &ver->protocol_version)) {

2 tabs then 4 spaces then "put_user"
3 tabs then 5 spaces then "&ver->"

using scripts/checkpatch.pl --strict should alert you to this.

And, either don't submit this until after 3.15-rc1 is out
and Greg KH starts taking patches again, or expect to be
very patient about getting any update on this.
