[PATCH 1/2] ACPI: EC: Drop EC noirq hooks to fix a regression

2017-07-11 Thread Lv Zheng
According to the bug report, though the busy polling mode can make noirq stages executed faster, it causes abnormal fan blowing up after a system resume (see link #1 for a video demonstration) on Lenovo ThinkPad X1 Carbon - the 5th Generation. The problem can be fixed by an upgraded EC firmware.
