Detecting the number of supported touches for a particular device used to be tricky, both because early forms of the driver didn't have a very good HID parser and because early hardware didn't always advertise the actual number. At the time, we added a block of code which would ensure that touch_max would always be equal to at least 1 on any touch device, and relied on setting touch_max to e.g. 2 only for the multitouch-capable exceptions. The common case has since flipped, and the driver and descriptors can reliably detect the number of touches supported by modern sensors. Because of this, it makes sense to remove the fixup code and instead place static declarations of "touch_max = 1" for these old devices. It isn't entirely clear if all 2-finger devices actually report a maximum number of touches so we leave these declarations still in place. For the eagle-eyed, the "> BAMBOO_PT" condition was originally equivalent to ">= TABLETPC", which is what the intent was. This commit doesn't have to consider the types introduced in the interim since they shouldn't be affected, hence why only the tablet PC definitions have been modified.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
