[PATCH v1 1/1] iio: cros_ec: Fix Kconfig dependency on CROS_EC_SENSORHUB

[Andy Shevchenko]

When CONFIG_CROS_EC_SENSORHUB is set to m, the IIO_CROS_EC_SENSORS_CORE
can't be built-in.

Fixes: 53067471188c ("iio / platform: cros_ec: Add cros-ec-sensorhub driver")

Looking again into .config actually puzzles me, there shouldn't be build
errors.

Trying again, text only this time. Sorry for the trouble.

This seems wrong.  IIO_CROS_EC_SENSORS_CORE should already be limited to m
if CROS_EC_SENSORHUB=m.

Note that I can not reproduce the problem in the bugzilla entry,
neither with mainline
nor with v5.13.6. And the configuration file published there looks fine and
already has IIO_CROS_EC_SENSORS_CORE=m.
