commit69dbdfffefupstream. The Bluetooth interface of the 2nd-gen Intuos Pro batches together four independent "frames" of finger data into a single report. Each frame is essentially equivalent to a single USB report, with the up-to-10 fingers worth of information being spread across two frames. At the moment the driver only calls `input_sync` after processing all four frames have been processed, which can result in the driver sending multiple updates for a single slot within the same SYN_REPORT. This can confuse userspace, so modify the driver to sync more often if necessary (i.e., after reporting the state of all fingers).

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.
