Can we have some consistency in the exported symbol naming,
we have two combinations now.

EXPORT_SYMBOL_GPL(gh_rm_notifier_register);
EXPORT_SYMBOL_GPL(get_gh_rm);

lets stick to one.

done.

How are we ensuring that gunyah driver is probed before this driver?



Which driver?

Am referring to gunyah.ko

TBH, gunyah.c should be merged as part of resource manager, and check if uuids and features in probe before proceeding further.

new line here would be nice.


done.
