When using MMIO with regmap, fast_io is implied. No need to set it again.

ps8640_aux_transfer_msg() programs the AUX address registers, starts the
AUX transfer, waits for SWAUX_SEND to clear, and reads the AUX status
register. Several of those regmap operations have return values, but the
function only checks a stale ret after the status read.
Propagate failures from the address write, transfer start, completion
poll, and status read. This avoids returning a transfer length when the
bridge register transaction or AUX completion wait failed.

devm_request_threaded_irq() automatically logs detailed error messages on

While being less compact, using named initializers allows to more easily see which members of the structs are assigned which value without having to lookup the declaration of the struct. And it's also more robust against changes to the struct definition. The mentioned robustness is relevant for a planned change to struct i2c_device_id that replaces .driver_data by an anonymous union. While touching all these arrays, unify usage of whitespace in the list terminator and drop trailing commas there. This patch doesn't modify the compiled arrays, only their representation in source form benefits. The former was confirmed with x86 and arm64 builds.

If the probe function returns an error after getting the I2C adapter for
DDC, the reference to the adapter is never released. Fix it by releasing
it in the bridge .destroy() handler.
There is no need to test the ddc pointer with !IS_ERR(), as
of_get_i2c_adapter_by_node() returns NULL on error.
