[PATCH] regulator: ab8500: tidy ab8500_regulator_get_mode()

[Dan Carpenter]

The indenting here is confusing.

Also we don't check "ret".  That isn't likely to cause a runtime issue
because if it fails here fails then we'd probably return -EINVAL at the
end anyway.  But it does introduce a static checker warning since "val"
is only inititialized on the success path.

    drivers/regulator/ab8500.c:429 ab8500_regulator_get_mode()
    error: uninitialized symbol 'val'.
