Subject: [PATCH] i2c: also convert placeholder function to return errno
Git-commit: 8be23aec0ee151de731626d5578973fde25b2285
Patch-mainline: v5.8 or v5.8-rc8 (next release)
References: git-fixes

All i2c_new_device-alike functions return ERR_PTR these days, but this
fallback function was missed.

Fixes: 2dea645ffc21 ("i2c: acpi: Return error pointers from i2c_acpi_new_device()")
