e17d787c51 V4L/DVB (12118): pvrusb2: Fix hardware scaling when used with cx25840
The cx25840 module requires that its VBI initialization entry point be
called in order for hardware-scaled video capture to work properly -
even if we don't care about VBI.  Making this behavior even more
subtle is that if the capture resolution is set to 720x480 - which is
the default that the pvrusb2 driver sets up - then the cx25840
bypasses the hardware scaler.  Therefore this problem does not
manifest itself until some other resolution, e.g. 640x480, is tried.
MythTV typically defaults to 640x480 or 480x480, which means that
things break whenever the driver is used with MythTV.

This all has been known for a while (since at least Nov 2006), but
recent changes in the pvrusb2 driver (specifically in regards to
sub-device support) caused this to break again.  VBI initialization
must happen *after* the chip's firmware is loaded, not before.  With
this fix, 24xxx devices work correctly again.

A related fix that is part of this changeset is that now we
re-initialize VBI any time after we issue a reset to the cx25840
driver.  Issuing a chip reset erases the state that the VBI setup
previously did.  Until the HVR-1950 came along this subtlety went
unnoticed, because the pvrusb2 driver previously never issued such a
reset.  But with the HVR-1950 we have to do that reset in order to
correctly transition from digital back to analog mode - and since the
HVR-1950 always starts in digital mode (required for the DVB side to
initialize correctly) then this device has never had a chance to work
correctly in analog mode!  Analog capture on the HVR-1950 has been
broken this *ENTIRE* time.  I had missed it until now because I've
usually been testing at the default 720x480 resolution which does not
require scaling...  What fun.  By re-initializing VBI after a cx25840
chip reset, correct behavior is restored.

tcm825x_remove is not necessarily called on module exit, it can also be

be removed on an embedded system, in practice this sensor driver can also
be used in e.g. a USB webcam where this is a perfectly acceptable thing
to do.

Make it very clear that this header should not be used for i2c drivers that

cdf7bfa892 V4L/DVB (12100): em28xx: make sure the analog GPIOs are set if we used a card hint
In cases where the board had a default USB ID, we would not indentify the
board until after the call to em28xx_set_mode().  As a result, for those
boards the analog GPIOs were not being set before probing the i2c bus for
devices (the probe would occur with the GPIOs being all high).

Make a call to em28xx_set_mode() so that the GPIOs are set properly before
probing the i2c bus for devices.

This problem was detected with the EVGA inDtube, where the tvp5150 is not
powered on unless GPIO1 is pulled low.

68237a0ff8 RDMA/nes: Fix FIN state handling under error conditions
During cluster testing, one QP was not closed, as FIN is not handled
properly when its rexmit count expires or in some cases when RST is is
received after sending FIN.  The reason is that the cm_id does not get
decremented under these conditions.

In nes_query_device(), max_qp_init_rd_atom is incorrectly set to
max_qp_wr.  This was found when a test application had a dapl async
event error.

0cf89dcdbc IB/ehca: Tolerate dynamic memory operations before driver load
Implement toleration of dynamic memory operations and 16 GB gigantic
pages, where "toleration" means that the driver can cope with dynamic
memory operations that happen before the driver is loaded.  While the
ehca driver is loaded, dynamic memory operations are still prohibited
by returning NOTIFY_BAD from the memory notifier.

On module load the driver walks through available system memory,
checks for available memory ranges and then registers the kernel
internal memory region accordingly.  The translation of address ranges
is implemented via a 3-level busmap.
