[PATCH 1/2] config.c: drop local variable

[PATCH 1/2] config.c: drop local variable

[Stefan Beller]

As `ret` is not used for anything except determining an early return,
we don't need a variable for that. Drop it.

While reading config code, I found 2 nits. Both improve readability,
no bugfix or feature.

As it is generally discouraged to have cleanup patch churn,
I checked master..pu to see any possible topics in flight conflicting
on config.c or submodule-config.c and there is nothing close by.

Thanks,
Stefan

[PATCH 2/2] submodule-config: don't shadow `cache`

[Stefan Beller]

Lots of internal functions in submodule-confic.c have a first parameter
`struct submodule_cache *cache`, which currently always refers to the
global variable `cache` in the file. To avoid confusion rename the
global `cache` variable.
