[PATCH 08/15] Input: synaptics-rmi4 - cleanup platform data

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

 



Update platform data documentation and remove unneeded/unused stuff in
platform data.

If these items are needed at some later point, they should be added
then.  Until that point, we should unclutter the code.
