drm: encoder_slave: use new I2C API

2020-06-19T07:20:21+00:00

i2c_new_client() is deprecated, use the replacement i2c_new_client_device(). Also, we have a helper to check if a driver is bound. Use it to simplify the code. Note that this changes the errno for a failed device creation from ENOMEM to ENODEV. No callers currently interpret this errno, though, so we use this condensed error check.

drm: encoder_slave: fix refcouting error for modules

2020-06-19T07:20:15+00:00

module_put() balances try_module_get(), not request_module(). Fix the error path to match that. Fixes: 2066facca4c7 ("drm/kms: slave encoder interface.") Signed-off-by: Wolfram Sang Reviewed-by: Emil Velikov Acked-by: Daniel Vetter Signed-off-by: Wolfram Sang

drm/kms-core: Use recommened kerneldoc for struct member refs

2017-01-25T15:30:34+00:00

I just learned that &struct_name.member_name works and looks pretty even. It doesn't (yet) link to the member directly though, which would be really good for big structures or vfunc tables (where the per-member kerneldoc tends to be long). Also some minor drive-by polish where it makes sense, I read a lot of docs ... v2: Review from Eric.

drm: fixes when i2c encoder slave mode_fixup is null.

2016-02-10T14:14:49+00:00

Avoid i2c slave encoder drivers to copy/paste code to implement functions that will only return true.

drm: encoder_slave: Don't use i2c_client->driver

2013-10-03T20:28:28+00:00

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)'. Signed-off-by: Lars-Peter Clausen Signed-off-by: Wolfram Sang

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. Signed-off-by: Kees Cook Acked-by: Paul Menzel Signed-off-by: Dave Airlie

drm: i2c encoder helper wrappers

2013-02-17T22:55:42+00:00

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. Signed-off-by: Rob Clark
