platform-drivers-x86 for v4.17-1
Dell SMBIOS driver fixed against memory leaks. The fujitsu-laptop driver is cleaned up and now supports hotkeys for Lifebook U7x7 models. Besides that the typo introduced by one of previous clean up series has been fixed. Specific to x86-based laptops HID device now supports KEY_ROTATE_LOCK_TOGGLE event which is emitted, for example, by Wacom MobileStudio Pro 13. Turbo MAX 3 technology is enabled for the rest of platforms that support Hardware-P-States feature which have core priority described by ACPI CPPC table. Mellanox on x86 gets better support of I2C bus in use including support of hotpluggable ones. Silead touchscreen is enabled on two tablet models, i.e Yours Y8W81 and I.T.Works TW701. From now on the second fan on Thinkpad P50 is supported. The topstar-laptop driver is reworked to support new models, in particular Topstar U931. Some of the changes had been already applied during v4.16 cycle and thus have a duplication here: -027d50ccd6
