The conversion from DocBook required some fixes:
- Now, the C files with the exported symbols also need to be
added. So, all headers need to be included twice: one to
get the structs/enums/.. and another one for the functions;
- Notes should use the ReST tag, as kernel-doc doesn't
recognizes it anymore;
- Identation needs to be fixed, as ReST uses it to identify
when a format "tag" ends.
- Fix the cross-references at the media controller description.

Move the contents of the media section at
DocBooks/DocBook/device-drivers.tmpl to a new ReST book.
For now, the contents is kept as-is. Next patches will fix
the warnings and add cross-references that were removed due to
the conversion.

The scale for ISDB-T was wrong too: it was inverted, and
on a relative scale.
Use a linear interpolation to make it look better.
The formula was empirically determined, using 3 frequencies
(175 MHz, 410 MHz and 800 MHz), measuring from -50dBm to
-12dBm in steps of 0.5dB.

Instead of using a relative frequency range, calibrate it to
show the results in dB. The callibration was done getting
samples with a signal generated from -50dBm to -12dBm,
incremented in steps of 0.5 dB, using 3 frequencies:
175 MHz, 410 MHz and 800 MHz. The modulated signal was
using QAM64, and it was used a linear interpolation of all
the results.

Appling the mask 0x0f to the immediate return of the call to
mb86a20s_readreg will always result in a positive value, meaning that the
check of ret < 0 will never work. Instead, check for a -ve return value
first, and then mask val with 0x0f.

This patch addresses CVE-2016-5400, a local DOS vulnerability caused by
a memory leak in the airspy usb device driver.
The vulnerability is triggered when more than 64 usb devices register
with v4l2 of type VFL_TYPE_SDR or VFL_TYPE_SUBDEV.A badusb device can
emulate 64 of these devices then through continual emulated
connect/disconnect of the 65th device, cause the kernel to run out of
RAM and crash the kernel.
The vulnerability exists in kernel versions from 3.17 to current 4.7.
The memory leak is caused by the probe function of the airspy driver
mishandeling errors and not freeing the corresponding control structures
when an error occours registering the device to v4l2 core.

The newly added mtk-vcodec driver produces a number of warnings in an
ARM allmodconfig build, mainly since it assumes that dma_addr_t is
32-bit wide:
mtk-vcodec/venc/venc_vp8_if.c: In function 'vp8_enc_alloc_work_buf':
mtk-vcodec/venc/venc_vp8_if.c:212:191: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
mtk-vcodec/venc/venc_h264_if.c: In function 'h264_enc_alloc_work_buf':
mtk-vcodec/venc/venc_h264_if.c:297:190: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
This rearranges the format strings and type casts to what they should
have been in order to avoid the warnings. e0f80d8d62f5 ("[media]
mtk-vcodec: fix two compiler warnings") fixed some of the problems that
were introduced at the same time, but missed two others.

The value 5 of the EEPROM_TS_MODE register (meaning dual tuner presence) is
only valid for AF9035 devices. For IT9135 devices it is invalid and led to a
false positive dual tuner mode detection with PCTV 79e.
Therefore on non-AF9035 devices and with value 5 the driver now defaults to
single tuner mode and outputs a regarding info message to log.
This fixes Bugzilla bug #118561.

address
If a system configures the Nuvoton chip to use the alternative
EFM IO address (CR_EFIR2) then after probing the primary EFM IO
address (CR_EFIR) this region is not released.
If a driver for another function of the Nuvoton Super I/O
chip uses the same probing mechanism then it will hang if
loaded after the nuvoton-cir driver.
This was reported for the nct6775 hwmon driver.
Fix this by properly releasing the region after probing CR_EFIR.
This regression was introduced with kernel 4.6 so cc it to stable.

The wait_event() call in dvb_unregister_frontend() waits synchronously
for other tasks to free a file descriptor, but it does that while
holding several mutexes. That alone is a bad idea, but if one user
process happens to keep a (defunct) file descriptor open indefinitely,
the kernel will correctly detect a hung task:

The newly added FCP support in the vsp1 driver causes a link error

drivers/media/built-in.o: In function `vsp1_probe':

We already have a conditional dependency on FCP that requires
it for ARM64, so for all others we just have to prevent setting
RENESAS_VSP1=y when RENESAS_FCP=m by extending the FCP dependency.

slightly incorrect #ifdef guards:
drivers/media/platform/vsp1/vsp1_drv.c:525:12: error: 'vsp1_pm_runtime_resume' defined but not used [-Werror=unused-function]
drivers/media/platform/vsp1/vsp1_drv.c:516:12: error: 'vsp1_pm_runtime_suspend' defined but not used [-Werror=unused-function]
This removes the existing #ifdef and instead marks all four
PM functions as __maybe_unused.

Now that the frame rate can be properly set, this commit adds support
for S_PARM and G_PARM.

Instead of using two tables to estimate the temporal decimation
factor, use a formula. This allows to get the closest fps, which
sounds better than the current tables.
Also, the current code doesn't store the real framerate.
This patch fixes the above issues.
[Ezequiel:
- introduce a TW686X_MAX_FPS macro for max_fps.
- use hweight_long instead of open coding the set bits count.]

My static checker complains that if adap->props.num_frontends is 0 then
"ret" is uninitialized. I don't think that can happen. But "ret" is
always zero here so we can just remove the condition.
This extra check was added in commit 0d3ab8410dcb ('[media] dvb core:
must check dvb_create_media_graph()').

Add the USB ID for Terratec Cinergy S2 Rev.3 (0ccd:0102).
Curiously dvb-usb-ids included already the USB ID for TERRATEC_CINERGY_S2_R3 even if the device was not supported.

Tuning a card with Sony ASCOT2E produces the following error:
kernel: i2c i2c-9: wr reg=0006: len=11 is too big!
MAX_WRITE_REGSIZE is defined as 10, buf[MAX_WRITE_REGSIZE + 1] buffer is
used in ascot2e_write_regs().
The problem is that exactly 10 bytes are written in ascot2e_set_params():
/* Set BW_OFFSET (0x0F) value from parameter table */
data[9] = ascot2e_sett[tv_system].bw_offset;
ascot2e_write_regs(priv, 0x06, data, 10);
The test in write_regs is as follows:
if (len + 1 >= sizeof(buf))
10 + 1 = 11 and that would be exactly the size of buf. Since 10 bytes +
buf[0] = reg would seem to fit into buf[], this shouldn't be an error.

There is a error message within devm_ioremap_resource
already, so remove the dev_err call to avoid redundant

In case of error, the function devm_clk_get() returns ERR_PTR()
and not returns NULL. The NULL test in the return value check
should be replaced with IS_ERR().
