From af4c0a431c24a38519815a6e44325d29f9073da7 Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Fri, 17 Feb 2017 19:48:56 -0600 Subject: [PATCH] ec/ene_kb3940q: correct ACPI battery data fed into ToString() ToString() requires the input buffer data to be null-terminated, but the data returned by the EC is not, leading Windows to fail to report any battery data at all. Correct this by concatenating a null terminator (0x00) to the end of the buffer data before inputting to ToString() where needed TEST: boot Windows on google/butterfly, observe battery data reported correctly.
