commit184eccd403upstream. In the generic code path, HID_DG_CONTACTMAX was previously only read from the second byte of report 0x23. Another report (0x82) has the HID_DG_CONTACTMAX in the higher nibble of the third byte. We should support reading the value of HID_DG_CONTACTMAX no matter what report we are reading or which position that value is in. To do this we submit the feature report as a event report using hid_report_raw_event(). Our modified finger event path records the value of HID_DG_CONTACTMAX when it sees that usage.

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.
