As usual, we can drop the drm_dev_put() and need to embed the drm_device. Since it's so few, also go right ahead and leave drm_device->dev_private set to NULL, so that we always use the container_of() upcast, which is faster anyway. Acked-by:

Komeda uses the component framework, which does open/close a new devres group around all the bind callbacks. Which means we can use devm_ functions for managing the drm_device cleanup, with leaking stuff in case of deferred probes or other reasons to unbind components, or the component_master. Also note that this fixes a double-free in the probe unroll code, bot drm_dev_put and kfree(kms) result in the kms allocation getting freed. Aside: komeda_bind could be cleaned up a lot, devm_kfree is a bit redundant. Plus I'm not clear on why there's suballocations for mdrv->mdev and mdrv->kms. Plus I'm not sure the lifetimes are correct with all that devm_kzalloc usage ... That structure layout is also the reason why komeda still uses drm_device->dev_private and can't easily be replaced with a proper container_of upcasting. I'm pretty sure that there's endless amounts of hotunplug/hotremove bugs in there with all the unprotected dereferencing of drm_device->dev_private. Reviewed-by:

We already have it in v3d_dev->drm.dev with zero additional pointer chasing. Personally I don't like duplicated pointers like this because: - reviewers need to check whether the pointer is for the same or different objects if there's multiple - compilers have an easier time too To avoid having to pull in some big headers I implemented the casting function as a macro instead of a static inline. Typechecking thanks to container_of still assured. But also a bit a bikeshed, so feel free to ignore. v2: More parens for v3d_to_pdev macro (checkpatch) Acked-by:

Daniel Vetter authored
Add a new macro helper to combine the usual init sequence in drivers, consisting of a kzalloc + devm_drm_dev_init + drmm_add_final_kfree triplet. This allows us to remove the rather unsightly drmm_add_final_kfree from all currently merged drivers. The kerneldoc is only added for this new function. Existing kerneldoc and examples will be udated at the very end, since once all drivers are converted over to devm_drm_dev_alloc we can unexport a lot of interim functions and make the documentation for driver authors a lot cleaner and less confusing. There will be only one true way to initialize a drm_device at the end of this, which is going to be devm_drm_dev_alloc. v2: - Actually explain what this is for in the commit message (Sam) - Fix checkpatch issues (Sam) Acked-by:

While we support using both tx slots for sideband transmissions, it appears that DisplayPort devices in the field didn't end up doing a very good job of supporting it. From section 5.2.1 of the DP 2.0 specification: There are MST Sink/Branch devices in the field that do not handle interleaved message transactions. To facilitate message transaction handling by downstream devices, an MST Source device shall generate message transactions in an atomic manner (i.e., the MST Source device shall not concurrently interleave multiple message transactions). Therefore, an MST Source device shall clear the Message_Sequence_No value in the Sideband_MSG_Header to 0. This might come as a bit of a surprise since the vast majority of hubs will support using both tx slots even if they don't support interleaved message transactions, and we've also been using both tx slots since MST was introduced into the kernel. However, there is one device we've had trouble getting working consistently with MST for so long that we actually assumed it was just broken: the infamous Dell P2415Qb. Previously this monitor would appear to work sometimes, but in most situations would end up timing out LINK_ADDRESS messages almost at random until you power cycled the whole display. After reading section 5.2.1 in the DP 2.0 spec, some closer investigation into this infamous display revealed it was only ever timing out on sideband messages in the second TX slot. Sure enough, avoiding the second TX slot has suddenly made this monitor function perfectly for the first time in five years. And since they explicitly mention this in the specification, I doubt this is the only monitor out there with this issue. This might even explain explain the seemingly harmless garbage sideband responses we would occasionally see with MST hubs! So - rewrite our sideband TX handlers to only support one TX slot. In order to simplify our sideband handling now that we don't support transmitting to multiple MSTBs at once, we also move all state tracking for down replies from mstbs to the topology manager.
