As I mentioned in the last version, don't wrap the Fixes tag. It can go
over 75 char.

	Fixes tag: Fixes: 047e0030f1e6 ("igb: add new data structure
for handling
		Has these problem(s):
			- Subject has leading but no trailing 	parentheses
			- Subject has leading but no trailing quotes

Also, please remember to indicate revisions with change log when
resending. i.e. this should've been 'v2'. Can you fix the above and
resend as v3?
