Subject: HID: amd_sfh: Enable operating mode
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=3a807f3ff9eaaeead81576c5a72d226d519a2fe7;p=thirdparty%2Fkernel%2Flinux.git

HID: amd_sfh: Enable operating mode

Add changes to enable operating modes in the driver to allow the FW to
activate and retrieve data from relevant sensors. This enables the FW to
take necessary actions based on the operating modes.
