From 34570a898eef01b5311bfc9c448877eb717d3285 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 23 Aug 2021 12:32:21 +0300 Subject: platform/x86: hp_accel: Remove _INI method call According to ACPI specification the _INI method must be called when device is enumerated first time. After that there is no need to repeat the procedure. Convert the lis3lv02d_acpi_init() to be a stub (Note, we may not remove it because it is called unconditionally by the accelerometer main driver).
