Lauri Tirkkonen a45f15808f HID: lenovo: fixup Lenovo Yoga Slim 7x Keyboard rdesc
The keyboard of this device has the following in its report description
for Usage (Keyboard) in Collection (Application):

	# 0x15, 0x00,                    //  Logical Minimum (0)                52
	# 0x25, 0x65,                    //  Logical Maximum (101)              54
	# 0x05, 0x07,                    //  Usage Page (Keyboard)              56
	# 0x19, 0x00,                    //  Usage Minimum (0)                  58
	# 0x29, 0xdd,                    //  Usage Maximum (221)                60
	# 0x81, 0x00,                    //  Input (Data,Arr,Abs)               62

Since the Usage Min/Max range exceeds the Logical Min/Max range,
keypresses outside the Logical range are not recognized. This includes,
for example, the Japanese language keyboard variant's keys for |, _ and
\.

Fixup the report description to make the Logical range match the Usage
range, fixing the interpretation of keypresses above 101 on this 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 reStructuredText 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.
