hid-multitouch currently runs GET_REPORT for Contact Max and again to retrieve the Win8 blob. If both are within the same report, the Resolution Multiplier code calls GET_FEATURE again and this time, possibly due to timing, it causes the ILITEK-TP device interpret the GET_FEATURE as an instruction to change the mode and effectively stop the device from functioning as expected. Notably: the device doesn't even have a Resolution Multiplier so it shouldn't be affected by any of this at all. Fix this by making sure we only execute GET_REPORT if there is a Resolution Multiplier in the respective report. Where the HID_QUIRK_NO_INIT_REPORTS field is set we just bail out immediately. This shouldn't be triggered by any real device anyway. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net> Tested-by: Wen He <wen.he_1@nxp.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
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.
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.
