git submodule problem

[Erik Claij <klimclay@xxxxxxxxx>]

Dear git,

Changing branch with

    git checkout --recurse-submodules <branch>

does not work when the branch does contain a new submodule.

Cloning a repo without submodules in master but submodules in the 
<branch> will reproduce this problem.

Error

    fatal: not a git repository: 
../../.git/modules/module/esp32_peripherals
    fatal: could not reset submodule index

The alternative way does work

    git checkout <branch>
    git submodule update --init --recurse
    git clean -ffd

Best,

Erik Claij
