<content type='text'>
Fix firmware file names assignment in si2157 tuner, allow for running
devices without firmware files needed.

modprobe gives error: unknown chip version Si2147-A30 ROM 0x50
Device initialization is interrupted.

Caused by:
1. table si2157_tuners has swapped fields rom_id and required vs struct
   si2157_tuner_info.
2. both firmware file names can be null for devices with
   required == false - device uses build-in firmware in this case

Tested on this device:
	m07ca:1871 AVerMedia Technologies, Inc. TD310 DVB-T/T2/C dongle

<title>media: Kconfig: cleanup VIDEO_DEV dependencies</title>

<id>urn:sha1:9958d30f38b96fb763a10d44d18ddad39127d5f4</id>
<content type='text'>
media Kconfig has two entries associated to V4L API:
VIDEO_DEV and VIDEO_V4L2.

On Kernel 2.6.x, there were two V4L APIs, each one with its own flag.
VIDEO_DEV were meant to:
	1) enable Video4Linux and make its Kconfig options to appear;
	2) it makes the Kernel build the V4L core.

while VIDEO_V4L2 where used to distinguish between drivers that
implement the newer API and drivers that implemented the former one.

With time, such meaning changed, specially after the removal of
all V4L version 1 drivers.

At the current implementation, VIDEO_DEV only does (1): it enables
the media options related to V4L, that now has:

	menu "Video4Linux options"
		visible if VIDEO_DEV

	source "drivers/media/v4l2-core/Kconfig"
	endmenu

but it doesn't affect anymore the V4L core drivers.

The rationale is that the V4L2 core has a "soft" dependency
at the I2C bus, and now requires to select a number of other
Kconfig options:

	config VIDEO_V4L2
		tristate
		depends on (I2C || I2C=n) &amp;&amp; VIDEO_DEV
		select RATIONAL
		select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE
		default (I2C || I2C=n) &amp;&amp; VIDEO_DEV

In the past, merging them would be tricky, but it seems that it is now
possible to merge those symbols, in order to simplify V4L dependencies.

Let's keep VIDEO_DEV, as this one is used on some make *defconfig
configurations.

This is the only tuner driver that has "tuner-" on its name.

Rename it, in order to match all the other tuner drivers.

<title>spi: make remove callback a void function</title>

<content type='text'>
The value returned by an spi driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

DVB-C Annex C is mostly DVB-C Annex A with only minor differences, so
simply add it to the DVB-C Annex A switch case, so that tuning attempts
no longer result in -EINVAL.

Make digital tuning store the bandwidth in Hz in the private dev struct,
rather than the hardware-specific bandwidth property code, so that the
get_bandwidth() function returns the bandwidth in Hz, just as it already
does when using analog tuning.

<content type='text'>
Commit 98c65a3dac95 ("media: si2157: add support for 1.7MHz and 6.1
MHz") introduced two bugs: The 6.1MHz setting was always used for any
bandwidth less than 7MHz due to missing "else" keywords, and then the
setting was not specified as decimal 10, but as hexadecimal 0x10, which
makes the tuner refuse the tune command. In sum, it is not possible to
tune to any channels of less than 7MHz bandwidth anymore.

Add the missing "else" keywords and convert all bandwidth settings to
decimal to avoid any future decimal vs. hexadecimal confusion.

Remove the use of the undefined bandwidth setting 0x0f for bandwidths
greater than 8MHz, which is also refused by the tune command, in favour
of using the default bandwidth setting 8 for any bandwidths greater than
7MHz.
