Subject: [PATCH 4.20 036/183] mfd: cros_ec_dev: Add missing mfd_remove_devices() call in remove

4.20-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit 18e294ddafaeb80a1e2e10c9bd750a6cb8388d5b ]

The driver adds different MFD child devices via mfd_add_devices() and
hence it is required to call mfd_remove_devices() to remove MFD child
devices.
