The patch titled input: bcm5974: report ABS_MT events has been removed from the -mm tree. Its filename was input-bcm5974-report-abs_mt-events.patch This patch was dropped because other changes were merged, which wrecked this patch The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: input: bcm5974: report ABS_MT events From: "Henrik Rydberg" <rydberg@xxxxxxxxxxx> Make bcm5974 report raw multi-touch (MT) data in the form of ABS_MT events. The module parameter (nomt) may be used to turn off the effect of this patch. The module paremeter was added because all MT events bypass the input filtering and get sent directly to the X driver. Although it works as intended, without visible side effects, the stream of events is rather large, and since the bypassing is completely new behavior, I felt compelled to provide an option to turn it all off.
