Removing the drm_bridge_remove call should avoid a NULL dereference during list processing in drm_bridge_remove if the error path is ever taken.
The more natural approach would perhaps be to add a drm_bridge_add, but there are several other bridges that never call drm_bridge_add. Just removing the drm_bridge_remove is the easier fix.

This doesn't affect runtime because in the current code "idx" is always valid.
First, we read from "vgdev->capsets[idx].max_size" before checking whether "idx" is within bounds. And secondly the bounds check is off by one so we could end up reading one element beyond the end of the vgdev->capsets[] array.

commit efdfeb079cc3 ("regulator: fixed: Convert to use GPIO descriptor only") switched to use gpiod_get() to look up the regulator from the gpiolib core whether that is device tree or boardfile.
This meant that we activate the code in a603a2b8d86e ("gpio: of: Add special quirk to parse regulator flags") which means the descriptors coming from the device tree already have the right inversion and open drain semantics set up from the gpiolib core.
As the fixed regulator was inspected again we got the inverted inversion and things broke.
Fix it by ignoring the config in the device tree for now: the later patches in the series will push all inversion handling over to the gpiolib core and set it up properly in the boardfiles for legacy devices, but I did not finish that for this kernel cycle.

A quirk in snd-usb-audio was added to automate setting sample rate to 4800k and remove the previously exposed nonfunctional microphone for the Bowers & Wilkins PX: commit 240a8af929c7c57dcde28682725b29cf8474e8e5 https://lore.kernel.org/patchwork/patch/919689/
However the headphones where updated shortly after that to remove the unintentional microphone functionality. I guess because of this the headphones now crash when connecting them via USB while the quirk is active. Dmesg:
snd-usb-audio: probe of 2-3:1.0 failed with error -22 usb 2-3: 2:1: cannot get min/max values for control 2 (id 2)
This patch removes the microfone and allows the headphones to connect and work out of the box. It is based on the current mainline kernel and successfully applied an tested on my machine (4.18.10.arch1-1).

Fixes two problems introduced as early as commit 03aef4b6dc12 ("Staging: comedi: add ni_mio_common code"): (1) Ensures that the last four bits of NISTC_RTSI_TRIGB_OUT_REG register is not unduly overwritten on e-series devices. On e-series devices, the first three of the last four bits are reserved. The last bit defines the output selection of the RGOUT0 pin, otherwise known as RTSI_Sub_Selection. For m-series devices, these last four bits are indeed used as the output selection of the RTSI7 pin (and the RTSI_Sub_Selection bit for the RGOUT0 pin is moved to the RTSI_Trig_Direction register. (2) Allows all 4 RTSI_BRD lines to be treated as valid sources for RTSI lines.
This patch also cleans up the ni_get_rtsi_routing command for readability.

Jerry Zuo pointed out a rather obscure hotplugging issue that it seems I accidentally introduced into DRM two years ago.
Pretend we have a topology like this:
|- DP-1: mst_primary |- DP-4: active display |- DP-5: disconnected |- DP-6: active hub |- DP-7: active display |- DP-8: disconnected |- DP-9: disconnected
If we unplug DP-6, the topology starting at DP-7 will be destroyed but it's payloads will live on in DP-1's VCPI allocations and thus require removal. However, this removal currently fails because drm_dp_update_payload_part1() will (rightly so) try to validate the port before accessing it, fail then abort. If we keep going, eventually we run the MST hub out of bandwidth and all new allocations will start to fail (or in my case; all new displays just start flickering a ton).
We could just teach drm_dp_update_payload_part1() not to drop the port ref in this case, but then we also need to teach drm_dp_destroy_payload_step1() to do the same thing, then hope no one ever adds anything to the that requires a validated port reference in drm_dp_destroy_connector_work(). Kind of sketchy.
So let's go with a more clever solution: any port that drm_dp_destroy_connector_work() interacts with is guaranteed to still exist in memory until we say so. While said port might not be valid we don't really care: that's the whole reason we're destroying it in the first place! So, teach drm_dp_get_validated_port_ref() to use the all mighty current_work() function to avoid attempting to validate ports from the context of mgr->destroy_connector_work. I can't see any situation where this wouldn't be safe, and this avoids having to play whack-a-mole in the future of trying to work around port validation.
