Elsewhere we distinguish count == 0 with -ENOENT.

Is there is an example? I think it is suitable for its internal check 
to translate -ENOENT to count 0, because no phys property means no
phy. For a get helper with optional semantics. I think it is fine
to return 0.

This the brief list of what I roughly grepped with word "count" in the name.

gpiod_count()
of_hte_req_count()
i2c_acpi_resource_count()
ice_sriov_set_msix_vec_count()
reset_control_get_count()
