platform/x86: asus-wmi: Ignore WMI events with code 0x79
On some Asus devices, e.g. the T100TA, when the charger is connected we not only get a WMI event with code 0x58, but immediately after that event we also get an even with code 0x79. This is likely related to these devices having an Asus WMI device with a device-id of 0x00120066, which seems to provide some sort of charger-type info. The T100TA charger over a micro-USB connector, the embedded- controller register read when calling asus_wmi_get_devstate(0x00120066) returns different values when connected to a USB port (max 500mA charging) vs when connected to a 2A capable wall-charger. But the AML code reading this mangles the return value so that we can no longer tell the difference. So for now the meaning of the value return when getting the status of device-id 0x00120066 is unclear. This commit adds a key-mapping of code 0x79 to KE_IGNORE, silencing the kernel logging the following message every time the charger is plugged-in: [ 79.639548] asus_wmi: Unknown key 79 pressed Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
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.
