If anyone has any objections, please let me know. ------------------ From: Alok Tiwari [ Upstream commit a8934352ba01081c51d2df428e9d540aae0e88b5 ] The battery manufacturer string was incorrectly null terminated using bat_model instead of bat_manu. This could result in an unintended write to the wrong field and potentially incorrect behavior. fixe the issue by correctly null terminating the bat_manu string.
