Hi!

[ Upstream commit 2814646f76f8518326964f12ff20aaee70ba154d ]
Previous attempt to autodetect well-behaving patched firmware introduced in commit 46a0a2c96f0f ("HID: lenovo: Detect quirk-free fw on cptkbd and stop applying workaround") has shown that there are false-positives on original firmware (on both 1st gen and 2nd gen keyboards) which causes the middle button click workaround to be mistakenly disabled.
This commit adds explicit parameter to sysfs to control this workaround.
Should this go to stable? We have stream of lenovo workarounds, maybe -stable should wait for upstream to solve this.
Plus it should really have documentation.
Oh and we normally solve this stuff with module parameters, so that it can be fixed during bootup.
Best regards, Pavel
