X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e0ba38765c1d1d670246d6f6c518594aa8e62587;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

tools/kvm_stat: fix misc glitches

Addresses
- eliminate extra import
- missing variable initialization
- type redefinition from int to float
- passing of int type argument instead of string
- a couple of PEP8-reported indentation/formatting glitches
- remove unused variable drilldown in class Tui
