Two patches are supplied, booth are supposed to be applied against my
previous ones, which are added to the -mm-tree.
The first one is proposed by Dmitry Torokhov, I have just made some
changes so it applied to my previous changes, and I tried it out.
The second one decreases the number of I2C transactions transferred by
the driver. A unnecessary one during probe and an unnecessary power down
during each poll for coordinates are removed. The chip is explicitly
powered down before waiting for interrupts.
