[ Upstream commit 38a38f5a36da9820680d413972cb733349400532 ]
When support for Silead touchscreens was orginal added some touchscreens with older firmware versions only supported 5 fingers and this was made the default requiring the setting of a "silead,max-fingers=10" uint32 device-property for all touchscreen models which do support 10 fingers.
There are very few models with the old 5 finger fw, so in practice the setting of the "silead,max-fingers=10" is boilerplate which needs to be copy and pasted to every touchscreen config.
Reporting that 10 fingers are supported on devices which only support 5 fingers doesn't cause any problems for userspace in practice, since at max 4 finger gestures are supported anyways. Drop the max_fingers configuration and simply always assume 10 fingers.
This does not fix a serious bug, should not be in stable.
This patch is necessary for clean backporting of new DMI quirks added to drivers/platform/x86/touchscreen_dmi.c, so IMHO it does make sense as a stable series patch.
That's likely not reason it ended up it autosel, but why not. "Stable-dep-of" tag would be nice in that case.
Best regards, Pavel
