71dfb744bd drm: fixes when i2c encoder slave mode_fixup is null.
Avoid i2c slave encoder drivers to copy/paste code to implement functions that will
only return true.

3ee81b7aef drm: encoder_slave: Don't use i2c_client->driver
The 'driver' field of the i2c_client struct is redundant and is going to be
removed. The results of the expressions 'client->driver.driver->field' and
'client->dev.driver->field' are identical, so replace all occurrences of the
former with the later. To get direct access to the i2c_driver struct use
'to_i2c_driver(client->dev.driver)'.

d1fd3ddc46 drm: refactor call to request_module
This reduces the size of the stack frame when calling request_module().
Performing the sprintf before the call is not needed.

a7c47d6dc4 drm: i2c encoder helper wrappers
Simplify life for drivers using an encoder-slave, so that they can make
their drm_encoder_helper_funcs const, rather than needing to dynamically
allocate and populate them.

e0cd360813 gpu: add module.h to drivers/gpu files as required.
So that we don't get build failures once the implicit module.h
presence is removed.

a1e09b6259 drm/kms: Simplify setup of the initial I2C encoder config.
In most use cases the driver will be using the same static config all
the time: interpreting i2c_board_info::platform_data as the default
config we can can save the GPU driver a redundant set_config() call.

2066facca4 drm/kms: slave encoder interface.
Define some helper functions to make easier to detach a KMS encoder
implementation from the drm module of the GPU it's used in. This is
mainly useful for some external I2C encoders known to be present on
cards with GPUs from several different manufacturers.
