[media] smiapp: Fully probe the device in probe
In the case of platform data, ISPs that provide clocks to the sensor must
probe before the sensor does. Accessing the sensor does require the clocks,
and thus, probe cannot access the sensor in such a system.
This limitation does not exist in the case of the DT. Perform all
initialisation except Media entity initialisation, link creation and
sub-device registration in probe.

[media] uvcvideo: Add GUID for BGR 8:8:8
The Magewell XI100DUSB-HDMI[1] video capture device reports the pixel
format "
e436eb7d-524f-11ce-9f53-
0020af0ba770". This is its GUID for
BGR 8:8:8.
The UVC 1.5 spec[2] only defines GUIDs for YUY2, NV12, M420 and I420.
This seems to be an extension documented in the Microsoft Windows Media
Format SDK[3] - or at least the Media Format SDK was the only hit that
Google gave when searching for the GUID. This Media Format SDK defines
this GUID as corresponding to `MEDIASUBTYPE_RGB24`. Note though, the
XI100DUSB outputs BGR e.g. byte-reversed. I don't know if its the
capture device in error or Microsoft mean BGR when they say RGB.

Here is a set of patches to tackle that problem.

"The highlights this merge window include:
- Allow target fabric drivers to function as built-in. (Roland)
- Fix tcm_loop multi-TPG endpoint nexus bug. (Hannes)
- Move per device config_item_type into se_subsystem_api, allowing
configfs attributes to be defined at module_init time. (Jerome +
nab)
- Convert existing IBLOCK/FILEIO/RAMDISK/PSCSI/TCMU drivers to use
external configfs attributes. (nab)
- A number of iser-target fixes related to active session + network
portal shutdown stability during extended stress testing. (Sagi +
Slava)
- Dynamic allocation of T10-PI contexts for iser-target, fixing a
potentially bogus iscsi_np->tpg_np pointer reference in >= v3.14
code. (Sagi)
- iser-target performance + scalability improvements. (Sagi)
- Fixes for SPC-4 Persistent Reservation AllRegistrants spec
compliance. (Ilias + James + nab)
- Avoid potential short kern_sendmsg() in iscsi-target for now until
Al's conversion to use msghdr iteration is merged post -rc1.
(Viro)
Also, Sagi has requested a number of iser-target patches (9) that
address stability issues he's encountered during extended stress
testing be considered for v3.10.y + v3.14.y code. Given the amount of
LOC involved, it will certainly require extra backporting effort.
Apologies in advance to Greg-KH & Co on this. Sagi and I will be
working post-merge to ensure they each get applied correctly"

Pull x86 apic updates from Thomas Gleixner:
"After stopping the full x86/apic branch, I took some time to go
through the first block of patches again, which are mostly cleanups
and preparatory work for the irqdomain conversion and ioapic hotplug
support.
Unfortunaly one of the real problematic commits was right at the
beginning, so I rebased this portion of the pending patches without
the offenders.
It would be great to get this into 3.19. That makes reworking the
problematic parts simpler. The usual tip testing did not unearth any
issues and it is fully bisectible now.
I'm pretty confident that this wont affect the calmness of the xmas
season.
Changes:
- Split the convoluted io_apic.c code into domain specific parts
(vector, ioapic, msi, htirq)
- Introduce proper helper functions to retrieve irq specific data
instead of open coded dereferencing of pointers
- Preparatory work for ioapic hotplug and irqdomain conversion
- Removal of the non functional pci-ioapic driver
- Removal of unused irq entry stubs
- Make native_smp_prepare_cpus() preemtible to avoid GFP_ATOMIC
allocations for everything which is called from there.
- Small cleanups and fixes"
