Thanks for comment. > Then this should have been [PATCH v2], and the fixed version [PATCH > v3] 2nd patch(Additional patch) not include 1st patch(RFC PATCH). And the 1st patch has been merged into 'staging-next'. Now I can't decide. a) Add only version information to the 2nd patch. b) Merge the 1st and 2nd patches. Which is better for v3? -- Kohada Tetsuhiro <Kohada.Tetsuhiro@xxxxxxxxxxxxxxxxxxxxxxxxxxx>
