Subject: [PATCH] soft_tap.patch
Hi all.
I'm seeing a behavior in my freerunner where light taps on the
touchscreen are not registered as clicks by the kernel even though the
base hardware does report clicking events. I'm seeing the kernel
generate extra "unclick" events in these cases. It looks like in the
driver, an unclick event is processed before the click event, thus
suppressing the click from ever being generated. I'm attaching a patch
that addresses this. I'm now able to type much faster on the matchbox
keyboard, even when using my fingertips instead of fingernails.
