A linter checks the odd number of key and value pairs for common logger libraries:
go install github.com/timonwong/logrlint/cmd/logrlint

-debug string
debug flags, any subset of "fpstv"
-disable value
comma-separated list of disabled logger checker (klog,logr,zap)
-disableall
disable all logger checkers
-enable value
comma-separated list of enabled logger checker (klog,logr,zap) (default klog,logr,zap)
-fix
apply all suggested fixes
-flags
