If anyone has any objections, please let me know. ------------------ From: Osama Khan [ Upstream commit 163ca80013aafb6dc9cb295de3db7aeab9ab43f8 ] Added support for HP ProBook 440 G4 laptops by including the accelerometer orientation quirk for that device. Testing was performed based on the axis orientation guidelines here: https://www.kernel.org/doc/Documentation/misc-devices/lis3lv02d which states "If the left side is elevated, X increases (becomes positive)". When tested, on lifting the left edge, x values became increasingly negative thus indicating an inverted x-axis on the installed lis3lv02d chip. This was compensated by adding an entry for this device in hp_accel.c specifying the quirk as x_inverted. The patch was tested on a ProBook 440 G4 device and x-axis as well as y and z-axis values are now generated as per spec.
