From a3c42a467a254a17236ab817d5c7c6bc054e4f84 Mon Sep 17 00:00:00 2001 From: Hui Wang Date: Tue, 8 Nov 2016 16:13:23 +0800 Subject: [PATCH] platform/x86: thinkpad_acpi: Adding new hotkey ID for Lenovo thinkpad Recently we met an issue on lots of Lenovo thinkpad laptops (those laptops are not released to market yet), the issue is that the thinkpad_acpi.ko can't be automatically loaded as before. Through debugging, we found the HKEY_HID is LEN0268 instead of LEN0068 on those machines, and the MHKV is 0x200 instead of 0x100. So adding the new ID into the driver.
