max1720x_battery: check gauge_type before accessing max_m5 functionsandroid-u-qpr3-beta-2_r0.7android-u-qpr3-beta-2_r0.6android-u-qpr3-beta-2_r0.5android-u-qpr3-beta-2_r0.4android-u-qpr3-beta-2_r0.3android-u-qpr3-beta-2_r0.2android-15-dp-2_r0.6android-15-dp-2_r0.5android-15-dp-2_r0.3android-15-dp-2_r0.2android-15-dp-2_r0.1
This file handles both max77759 and max17201 FG, only max77759 FG allows
accesses to max_m5 related functions, adds gauge type checking to prevent kernel panic
