03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from

mfd: various: Use of_property_present() for testing DT property presence 2023-04-26T10:40:32+00:00 Rob Herring robh@kernel.org 2023-03-10T14:47:12+00:00 1ba58fbbe619125af113d0583c4b6bade94168d1 It is preferred to use typed property access functions (i.e. of_property_read_<type> functions) rather than low-level of_get_property/of_find_property functions for reading properties. As part of this, convert of_get_property/of_find_property calls to the recently added of_property_present() helper when we just want to test for presence of a property and nothing more.
