LG touchscreen (1fd2:8001) stops working after reboot: [ 4.859153] i2c_hid i2c-SAPS2101:00: i2c_hid_get_input: incomplete report (64/66) [ 4.936070] i2c_hid i2c-SAPS2101:00: i2c_hid_get_input: incomplete report (64/66) [ 9.948224] i2c_hid i2c-SAPS2101:00: failed to reset device. The device in question stops working after receives SLEEP, ON, SLEEP commands in a short period. The scenario is like this: - Once the desktop session closes, it also closed the hid device, so the device gets runtime suspended and receives a SLEEP command. - Before calling shutdown callback, it gets runtime resumed and received an ON command. - In the shutdown callback, it receives another SLEEP command. I failed to find a reliable interval between ON/SLEEP commands that can make it work, so let's simply disable runtime PM for the device.

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.
