The AVCL register, according to the datasheet, comes in increments of -0.2v between -4.4v (represented by 0x0) to -5.0v (represented by 0x3). The current calculation is done by adding the defined AVCL value in mV to -4400 and then dividing by 200 to get the register value. Unfortunately if I subtract -4400 from -4400 I get -8800, which divided by 200 gives me -44. If I instead subtract -4400 from -4400 I get 0, which divided by 200 gives me 0. Based on the datasheet this is the expected register value. Fixes: 83b7a8e7 ("drm/panel/panel-sitronix-st7701: Parametrize voltage and timing") Signed-off-by:

The drm_atomic_helper_check_wb_encoder_state() function doesn't use encoder for anything other than getting the drm_device instance. The function's description talks about checking the writeback connector state, not the encoder state. Moreover, there is no such thing as an encoder state, encoders generally do not have a state on their own. Rename the function to drm_atomic_helper_check_wb_connector_state() and change arguments to drm_writeback_connector and drm_atomic_state. Signed-off-by:

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it was merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. Soon the implicit includes are going to be removed. of_device.h isn't needed, but of.h is for of_node_put(). Reported-by:

Matthew Brost authored
No DRM scheduler changes required, drivers just return NULL in run_job vfunc. The rough consensus is that no helper or extra scaffolding is needed around long-running jobs and no further changes to drm-scheduler. At least for now. Other drivers that currently do long-running workloads have no plat to use drm-scheduler. Besides, the current consensus is that this solution of simply returning NULL to the run_job function should work without extra code duplication or complication. On top of that, this item was already a non-blocking one for upstreaming Xe, so let's move that to the 'Completed' section and revisit the long-running solution as a community after Xe is integrated in DRM.

It's been reported that DSI host driver's detach can be called without the attach ever happening: https://lore.kernel.org/all/20230412073954.20601-1-tony@atomide.com/ After reading the code, I think this is what happens: We have a DSI host defined in the device tree and a DSI peripheral under that host (i.e. an i2c device using the DSI as data bus doesn't exhibit this behavior). The host driver calls mipi_dsi_host_register(), which causes (via a few functions) mipi_dsi_device_add() to be called for the DSI peripheral. So now we have a DSI device under the host, but attach hasn't been called. Normally the probing of the devices continues, and eventually the DSI peripheral's driver will call mipi_dsi_attach(), attaching the peripheral. However, if the host driver's probe encounters an error after calling mipi_dsi_host_register(), and before the peripheral has called mipi_dsi_attach(), the host driver will do cleanups and return an error from its probe function. The cleanups include calling mipi_dsi_host_unregister(). mipi_dsi_host_unregister() will call two functions for all its DSI peripheral devices: mipi_dsi_detach() and mipi_dsi_device_unregister(). The latter makes sense, as the device exists, but the former may be wrong as attach has not necessarily been done. To fix this, track the attached state of the peripheral, and only detach from mipi_dsi_host_unregister() if the peripheral was attached. Note that I have only tested this with a board with an i2c DSI peripheral, not with a "pure" DSI peripheral. However, slightly related, the unregister machinery still seems broken. E.g. if the DSI host driver is unbound, it'll detach and unregister the DSI peripherals. After that, when the DSI peripheral driver unbound it'll call detach either directly or using the devm variant, leading to a crash. And probably the driver will crash if it happens, for some reason, to try to send a message via the DSI bus. But that's another topic. Tested-by:

I'm not familiar with the code to say if that path will always be ran in real life, but whether that is the case or not, I think it is good to initialize 'supported_status' to 0 to silence the warning (and possibly fix a bug).

The i2c_master_send/recv() functions return negative error codes or they return "len" on success. So the error handling here can be written as just normal checks for "if (ret < 0) return ret;". No need to complicate things. Btw, in this code the "len" parameter can never be zero, but even if it were, then I feel like this would still be the best way to write it.
