I'm testing an updated for-next with this fixed now and I'll push that

Apologies, and thanks for the catch. Rolled the fix from Arnd together with this
and the new one from Arvind. for-next had to be rebased to avoid introducing

Thank you Stephen,

Andy, you warned me about this and I had forgotten before I included it in next.

Would you like to drop this change, or drop the touchpad_store function?

How about "type".

OK, no, it's a false positive because tp_features.hotkey_tablet is assigned in
both places where in_tablet_mode is assigned, and if the former is 0 (global
scope), the function returns without calling pr_info.

Lyude, Henrique, please confirm.

Regardless, I'll add a patch to init in_tablet_mode to 0 so it is explicit - but
will not rebase as it isn't technically an error.

That's an uninitialized local variable. Not sure how I missed that. I'll

Yeah, I think I am innocent here. My patch was adding "select
INPUT_SPARCEKMAP" which is a library module and which I ensure to be
selectable as long as INPUT is enabled. I do not want to switch it
around into "depends on" since it is implementation detail and user
should not care.

Thanks.
