[PATCH AUTOSEL 6.2 15/18] Input: xpad - add constants for GIP interface numbers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Vicki Pfau <vi@xxxxxxxxxxx>

[ Upstream commit f9b2e603c6216824e34dc9a67205d98ccc9a41ca ]

Wired GIP devices present multiple interfaces with the same USB identification
other than the interface number. This adds constants for differentiating two of
them and uses them where appropriate
