2020-08-11drm/vmwgfx/stdu: Use drm_mode_config_resetDaniel Vetter
When converting to atomic the state reset was done by directly calling the functions, and before the modeset object was fully initialized. This means the various ->dev pointers weren't set up. After commit 51f644b40b4b794b28b982fdd5d0dd8ee63f9272 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Fri Jun 12 18:00:49 2020 +0200 drm/atomic-helper: reset vblank on crtc reset this started to oops because now we're trying to derefence drm_crtc->dev. Fix this up by entirely switching over to drm_mode_config_reset, called once everything is set up.

2020-08-11drm/vmwgfx: Fix two list_for_each loop exit testsDan Carpenter
These if statements are supposed to be true if we ended the list_for_each_entry() loops without hitting a break statement but they don't work. In the first loop, we increment "i" after the "if (i == unit)" condition so we don't necessarily know that "i" is not equal to unit at the end of the loop. In the second loop we exit when mode is not pointing to a valid drm_display_mode struct so it doesn't make sense to check "mode->type".

2020-08-11drm/vmwgfx: Use correct vmw_legacy_display_unit pointerDan Carpenter
The "entry" pointer is an offset from the list head and it doesn't point to a valid vmw_legacy_display_unit struct. Presumably the intent was to point to the last entry. Also the "i++" wasn't used so I have removed that as well. Fixes: d7e1958dbe4a ("drm/vmwgfx: Support older hardware.")

[Why] When changing pixel formats for HDR (e.g. ARGB -> FP16) there are configurations that change from 2 pipes to 1 pipe. In these cases, it seems that disconnecting MPCC and doing a surface update at the same time(after unlocking) causes some registers to be updated slightly faster than others after unlocking (e.g. if the pixel format is updated to FP16 before the new surface address is programmed, we get corruption on the screen because the pixel formats aren't matching).

2020-08-10spi: stm32: fix fifo threshold level in case of short transferAmelie Delaunay
When transfer is shorter than half of the fifo, set the data packet size up to transfer size instead of up to half of the fifo. Check also that threshold is set at least to 1 data frame.

2020-08-10spi: stm32h7: fix race condition at end of transferAntonio Borneo
The caller of stm32_spi_transfer_one(), spi_transfer_one_message(), is waiting for us to call spi_finalize_current_transfer() and will eventually schedule a new transfer, if available. We should guarantee that the spi controller is really available before calling spi_finalize_current_transfer(). Move the call to spi_finalize_current_transfer() _after_ the call to stm32_spi_disable().

2020-08-10EDAC/ie31200: Fallback if host bridge device is already initializedJason Baron
The Intel uncore driver may claim some of the pci ids from ie31200 which means that the ie31200 edac driver will not initialize them as part of pci_register_driver(). Let's add a fallback for this case to 'pci_get_device()' to get a reference on the device such that it can still be configured. This is similar in approach to other edac drivers.
