597f22d6aa ixgbe: add support for interrupts from X550 external PHY
This patch adds support for receiving interrupts from a external copper
PHY for the X550 part.  This includes enabling, detection as well as
re-enablement.

c3dc4c09f1 ixgbe: add X550 support for external PHY and forced 1G/10G support
This patch adds x550 external PHY interrupt and forced 1G/10G support.
This included enabling and handling LSC and thermal sensor interrupt.
ixgbe_handle_lasi() has been added for handling the interrupts received
over SDP0 from the external 10baseT PHY. ixgbe_enable_lasi_ext_t_x550em
and ixgbe_get_lasi_ext_t_x550em have been added to X550em to enable
mask and check interrupt flags for the external PHY.

Forced 1G/10G link speed is handled via ixgbe_mac_link_t_X550em.
ixgbe_seupt_mac_link_t_X550em sets up the internal PHY and external PHY
to either iXFI (10G) or KX (1G) based on the user selected auto
advertised link speed setting. Then sets up the external PHY auto
advertised link speed.

11e584cfb8 cpufreq: Don't allow updating inactive policies from sysfs
Later commits would change the way policies are managed today. Policies
wouldn't be freed on cpu hotplug (currently they aren't freed only for
suspend), and while the CPU is offline, the sysfs cpufreq files would
still be present.

User may accidentally try to update the sysfs files in following
directory: '/sys/devices/system/cpu/cpuX/cpufreq/'. And that would
result in undefined behavior as policy wouldn't be active then.

Apart from updating the store() routine, we also update __cpufreq_get()
which can call cpufreq_out_of_sync(). The later routine tries to update
policy->cur and starts notifying kernel about it.

9056a23ba1 [media] dvb-frontend: Replace timeval with ktime_t
struct timeval uses a 32-bit seconds representation which will
overflow in the year 2038 and beyond. This patch replaces
the usage of struct timeval with ktime_t which is a 64-bit
timestamp and is year 2038 safe.
This patch is part of a larger attempt to remove all instances
of 32-bit timekeeping variables (timeval, timespec, time_t)
which are not year 2038 safe, from the kernel.

6c1e45917d intel_pstate: Force setting target pstate when required
During initialization and exit it is possible that the target pstate
might not actually be set. Furthermore, the result can be that the
driver and the processor are out of synch and, under some conditions,
the driver might never send the processor the proper target pstate.

This patch adds a bypass or do_checks flag to the call to
intel_pstate_set_pstate. If bypass, then specifically bypass clamp
checks and the do not send if it is the same as last time check. If
do_checks, then, and as before, do the current policy clamp checks,
and do not do actual send if the new target is the same as the old.

d3525b632a [media] b2c2: Add option to skip the first 6 pid filters
The flexcop bridge chip has two banks of hardware pid filters -
an initial 6, and on some chip revisions an additional bank of 32.

A bug is present on the initial 6 - when changing transponders
one of two PAT packets from the old transponder would be included
in the initial packets from the new transponder. This usually
transpired with userspace programs complaining about services
missing, because they are seeing a PAT that they would not be
expecting. Running in full TS mode does not exhibit this problem,
neither does using just the additional 32.

This patch adds in an option to not use the inital 6 and solely use
just the additional 32, and enables this option for the SkystarS2
card. Other cards can be added as required if they also have
this bug.

The various messages are inconsistent with respect to any identifier
text that can be used to help isolate the desired information from a

The Foxconn K8M890-8237A has two PCI host bridges, and we can't assign

we incorrectly assign a sound card address (this example is from 1033299):

25e057fdde [media] ddbridge: Do not free_irq() if request_irq() failed
My static checker detected that free_irq() is called even after
request_irq() failed in ddb_probe(). In this case, the kernel may try to
free dev->pdev->irq although the IRQ is not assigned. This event rarely
occurs, but always introduces a warning if it happens.

"goto fail1" always results in disabling enabled MSI and releasing a
requested IRQ. It seems like the former handling is necessary. So I added
a conditional branch before the free_irq() (stat == 0 means request_irq()
succeeds).

28ffeebbb7 [media] bdisp: 2D blitter driver using v4l2 mem2mem framework
This v4l2 mem2mem driver is a 2D blitter for STMicroelectronics SoC.
It uses the v4l2 mem2mem framework.

The following features are supported and tested:
- Color format conversion (RGB32, RGB24, RGB16, NV12, YUV420P)
- Copy
- Scale
- Flip
- Deinterlace
- Wide (4K) picture support
- Crop

9c5a18a31b cfg80211: wext: clear sinfo struct before calling driver
Until recently, mac80211 overwrote all the statistics it could
provide when getting called, but it now relies on the struct
having been zeroed by the caller. This was always the case in
nl80211, but wext used a static struct which could even cause
values from one device leak to another.

Using a static struct is OK (as even documented in a comment)
since the whole usage of this function and its return value is
always locked under RTNL. Not clearing the struct for calling
the driver has always been wrong though, since drivers were
free to only fill values they could report, so calling this
for one device and then for another would always have leaked
values from one to the other.

Fix this by initializing the structure in question before the
driver method call.

This fixes https://bugzilla.kernel.org/show_bug.cgi?id=99691

6c72edab02 [media] dvb: dmx.h: don't use anonymous enums
There are several anonymous enums here, used via a typedef.

Well, we don't like typedefs on Kernel, so let's de-anonimize
those enums. Then, latter, we may be able to get rid of the
typedefs, at least from Kernelspace.

81a7c6d9bb [media] dvb: frontend.h: improve dvb_frontent_parameters comment
The comment for struct dvb_frontend_parameters is weird, as it
mixes delivery system name (ATSC) with modulation names
(QPSK, QAM, OFDM).

Use delivery system names there on the frequency comment, as this
is clearer, specially after 2GEN delivery systems.

While here, add comments at the union, to make live easier for ones
that may try to understand the convention used by the legacy API.

0df289a209 [media] dvb: Get rid of typedev usage for enums
The DVB API was originally defined using typedefs. This is against
Kernel CodingStyle, and there's no good usage here. While we can't
remove its usage on userspace, we can avoid its usage in Kernelspace.

So, let's do it.

This patch was generated by this shell script:

	for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done

While here, make CodingStyle fixes on the affected lines.
