I had not realized that this function was supposed to be the .release
callback for a device, only that it was not being called at all.
The runtime warning you get is obviously correct and you do need a
.release function in the device that will free the memory for the
cros_ec_dev structure when the last reference to the device goes away.
Please send a fix for this, replacing the incorrect devm_kzalloc with
a working allocation/deallocation.

I readded it because when cros_ec_dev is loaded as module, I get a
warning on dmesg when unloading:
"""Device 'cros_pd' [or 'cros_ec'] does not have a release() function,
it is broken and must be fixed."""
The warning comes from device_release(). Given I get a warning when I
remove the release function or when I leave it empty. Let's pull the
patch.
Sorry for the confusion,
Gwendal.

Gwendal, in PATCH v2 of https://patchwork.kernel.org/patch/10439449/
you mentioned that you readded the __remove to avoid a warning when built
as a module. Can you explain what's going on?
