[ Upstream commit 4405a214df146775338a1e6232701a29024b82e1 ]
Some x86/ACPI laptops with MIPI cameras have a INTC10DE or INTC10E0 ACPI device in the _DEP dependency list of the ACPI devices for the camera- sensors (which have flags.honor_deps set).
These devices are for an Intel Vision CVS chip for which an out of tree driver is available [1].
The camera sensor works fine without a driver being loaded for this ACPI device on the 2 laptops this was tested on:
ThinkPad X1 Carbon Gen 12 (Meteor Lake) ThinkPad X1 2-in-1 Gen 10 (Arrow Lake)
For now add these HIDs to acpi_ignore_dep_ids[] so that acpi_dev_ready_for_enumeration() will return true once the other _DEP dependencies are met and an i2c_client for the camera sensor will get instantiated.
