Unfortunately the register addresses are different, as well as the event codes and bit organization within the port related registers. Move ADP5589 Register defines from the header file into the main source file. Add new defines while making sure we don't break existing platform_data. Add register address translation, and turn device specific defines into variables. Introduce some helper functions and disable functions that doesn't exist on the added devices.

We'd allocate a smaller amount of data than sizeof(struct ff_device). The call to kcalloc() on the next line would fail but it would write the NULL return outside of the memory we just allocated causing data corruption. The call path is that uinput_setup_device() get ->ff_effects_max from the user and sets the value in the ->private_data struct. From there it is: -> uinput_ioctl_handler() -> uinput_create_device() -> input_ff_create(dev, udev->ff_effects_max); I've also changed ff_effects_max so it's an unsigned int instead of a signed int as a cleanup.

Also unregister misc device immediately upon disconnecting the port instead of waiting until last user drops off (refcounting in misc device code will make sure needed pieces stay around while they are needed) and make sure we are not holing holding serio_raw_mutex when registering/unregistering misc device. This should fix potential deadlock between serio_raw and misc device code uncovered by lockdep and reported by Thomas Tuttle.

To keep from overwriting this buffer and causing havoc, use snprintf() to guarantee we never write more than the buffer can hold. In addition, at least for my touchscreen, the number and size of objects was far too big to fit in a single 4K page. Therefore, this patch also trims some redundant framing text to leave more room for actual data.

This patch adddresses two issues: - some model also has debounce packets, but with a different signature than v3. Now we just check debounce for all v2 hardware. - due to different scanning methods the hardware uses, x and y ranges have to be calculated differently. And for some specific versions, we can just see them as custom-made, so set {x, y} the same values as Windows driver does.
