commit 2cc08800a6b9fcda7c7afbcf2da1a6e8808da725 upstream.
The serial number and tool type information that is reported by the tablet
while a pen is merely "in prox" instead of fully "in range" can be stale
and cause us to report incorrect tool information. Serial number, tool
type, and other information is only valid once the pen comes fully in range
so we should be careful to not use this information until that point.
In particular, this issue may cause the driver to incorectly report
BTN_TOOL_RUBBER after switching from the eraser tool back to the pen.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
