c3c3f1ae8b [media] cx231xx: add wrapper to get the i2c_adapter pointer
This is a preparation for mapping I2C_1_MUX_1 and I2C_1_MUX_3 later to the seperate
muxed i2c adapters.

Map mux adapters to I2C_1 for now.

Add local variables for i2c_adapters in dvb_init to get line lengths
shorter.

3a8fede115 mwifiex: restart rxreorder timer correctly
During 11n RX reordering, if there is a hole in RX table,
driver will not send packets to kernel until the rxreorder
timer expires or the table is full.
However, currently driver always restarts rxreorder timer when
receiving a packet, which causes the timer hardly to expire.
So while connected with to 11n AP in a busy environment,
ping packets may get blocked for about 30 seconds.

This patch fixes this timer restarting by ensuring rxreorder timer
would only be restarted either timer is not set or start_win
has changed.

37fa8716e2 [media] rc-main: fix lockdep splash for rc-main
lockdep reports a potential circular dependecy deadlock when registering input device.

Unlock mutex rc_dev->lock prior to calling ir_raw_event_register to avoid the circular
dependency since that function also calls input_register_device and rc_open.

2279948735 [media] af9005: fix kernel panic on init if compiled without IR
This patches fixes an ancient bug in the dvb_usb_af9005 driver, which
has been reported at least in the following threads:
https://lkml.org/lkml/2009/2/4/350
https://lkml.org/lkml/2014/9/18/558

If the driver is compiled in without any IR support (neither
DVB_USB_AF9005_REMOTE nor custom symbols), the symbol_request calls in
af9005_usb_module_init() return pointers != NULL although the IR
symbols are not available.

This leads to the following oops:

The prefered fix would be to convert the whole IR code to use the kernel IR
infrastructure (which wasn't available at the time this driver had been created).

Until anyone who still has this old hardware steps up an does the conversion,
fix it by not calling the symbol_request calls if the driver is compiled in
without the default IR symbols (CONFIG_DVB_USB_AF9005_REMOTE).
Due to the IR related pointers beeing NULL by default, IR support will then be disabled.

The downside of this solution is, that it will no longer be possible to
compile custom IR symbols (not using CONFIG_DVB_USB_AF9005_REMOTE) in.

Please note that this patch has NOT been tested with all possible cases.
I don't have the hardware and could only verify that it fixes the reported
bug.

8c5bcded11 [media] ds3000: fix LNB supply voltage on Tevii S480 on initialization
The Tevii S480 outputs 18V on startup for the LNB supply voltage and does not
automatically power down. This blocks other receivers connected
to a satellite channel router (EN50494), since the receivers can not send the
required DiSEqC sequences when the Tevii card is connected to a the same SCR.

This patch switches off the LNB supply voltage on initialization of the frontend.

Although the diffstat looks scary, it's just because of the removal of
 the dead code (s6000), thus it must not affect anything serious.
 Other than that, all small fixes.  The only core fix is zero-clear for

ae9e9c6aee ext4: make ext4_ext_convert_to_initialized() return proper number of blocks
ext4_ext_convert_to_initialized() can return more blocks than are
actually allocated from map->m_lblk in case where initial part of the
on-disk extent is zeroed out. Luckily this doesn't have serious
consequences because the caller currently uses the return value
only to unmap metadata buffers. Anyway this is a data
corruption/exposure problem waiting to happen so fix it.

4f879ca687 ext4: bail early when clearing inode journal flag fails
When clearing inode journal flag, we call jbd2_journal_flush() to force
all the journalled data to their final locations. Currently we ignore
when this fails and continue clearing inode journal flag. This isn't a
big problem because when jbd2_journal_flush() fails, journal is likely
aborted anyway. But it can still lead to somewhat confusing results so
rather bail out early.

bc16e47f03 igb: don't reuse pages with pfmemalloc flag
Incoming packet is dropped silently by sk_filter(), if the skb was
allocated from pfmemalloc reserves and the corresponding socket is
not marked with the SOCK_MEMALLOC flag.

Igb driver allocates pages for DMA with __skb_alloc_page(), which
calls alloc_pages_node() with the __GFP_MEMALLOC flag. So, in case
of OOM condition, igb can get pages with pfmemalloc flag set.

If an incoming packet hits the pfmemalloc page and is large enough
(small packets are copying into the memory, allocated with
netdev_alloc_skb_ip_align(), so they are not affected), it will be
dropped.

This behavior is ok under high memory pressure, but the problem is
that the igb driver reuses these mapped pages. So, packets are still
dropping even if all memory issues are gone and there is a plenty
of free memory.

In my case, some TCP sessions hang on a small percentage (< 0.1%)
of machines days after OOMs.

Fix this by avoiding reuse of such pages.

VMWare's e1000 implementation does not seem to support unicast filtering.
This can be observed by configuring a macvlan interface on eth0 in a VM in
VMWare Fusion 5.0.5, and trying to use that interface instead of eth0.
Tested on 3.16.

678fa12fb8 [media] sound: Update au0828 quirks table
The au0828 quirks table is currently not in sync with the au0828
media driver.

Syncronize it and put them on the same order as found at au0828
driver, as all the au0828 devices with analog TV need the
same quirks.

5d1f00a20d [media] sound: simplify au0828 quirk table
Add a macro to simplify au0828 quirk table. That makes easier
to check it against the USB IDs at drivers/media/usb/au0828/au0828-cards.c.
