Subject: checkpatch: warn when networking block comment lines don't start with *
X-Git-Tag: v3.11-rc1~99^2~232
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a605e32ebde25dc31f943fecb30e3e28079ccd06;p=platform%2Fupstream%2Fkernel-adaptation-pc.git

checkpatch: warn when networking block comment lines don't start with *

Some block comments in network are written as:

	/* block comment line 1
	   block comment line 2
	 */

Emit a warning on the "block comment line 2" because it should be

	/* block comment line 1
	 * block comment line 2
	 */

This warning is only emitted on the second line of a block comment.
