* Rename device state from 's' to 'dev'.
* Move single include to driver private header.
* Change error handling type of each function to one I tend use
nowadays.
* Remove dummy register write from init. Even Windows driver does this
multiple times remove it as I have never seen any I2C errors.
* Define I2C client pointer for each function and use it.
* Do not clean tuner ops during driver remove - not needed.

bind / unbind device from the driver currently.

The chips supported by the si2157 driver have two IF outputs (either

add an option to choose which output shall be used.

As this patch changes the default behaviour, the IF interface is
specified in each driver currently using si2157 driver. This is to
keep bisectability.

9b174527e7 [media] Add and use IS_REACHABLE macro
In the media drivers, the v4l2 core knows about all submodules
and calls into them from a common function. However this cannot
work if the modules that get called are loadable and the
core is built-in. In that case we get

drivers/built-in.o: In function `set_type':
drivers/media/v4l2-core/tuner-core.c:301: undefined reference to `tea5767_attach'
drivers/media/v4l2-core/tuner-core.c:307: undefined reference to `tea5761_attach'
drivers/media/v4l2-core/tuner-core.c:349: undefined reference to `tda9887_attach'
drivers/media/v4l2-core/tuner-core.c:405: undefined reference to `xc4000_attach'

This was working previously, until the IS_ENABLED() macro was used
to replace the construct like

 #if defined(CONFIG_DVB_CX24110) || (defined(CONFIG_DVB_CX24110_MODULE) && defined(MODULE))

with the difference that the new code no longer checks whether it is being
built as a loadable module itself.

To fix this, this new patch adds an 'IS_REACHABLE' macro, which evaluates
true in exactly the condition that was used previously. The downside
of this is that this trades an obvious link error for a more subtle
runtime failure, but it is clear that the change that introduced the
link error was unintentional and it seems better to revert it for
now. Also, a similar change was originally created by Trent Piepho
and then reverted by teh change to the IS_ENABLED macro.

Ideally Kconfig would be used to avoid the case of a broken dependency,
or the code restructured in a way to turn around the dependency, but either
way would require much larger changes here.

Fixes: 7b34be71db ("[media] use IS_ENABLED() macro")

856260a57c [media] xc5000: fix memory corruption when unplugging device
This patch addresses a regression introduced in the following patch:

commit 5264a522a5
Author: Shuah Khan <shuahkh@osg.samsung.com>
    [media] media: tuner xc5000 - release firmwware from xc5000_release()

The "priv" struct is actually reference counted, so the xc5000_release()
function gets called multiple times for hybrid devices.  Because
release_firmware() was always being called, it would work fine as expected
on the first call but then the second call would corrupt aribtrary memory.

Set the pointer to NULL after releasing so that we don't call
release_firmware() twice.

This problem was detected in the HVR-950q where plugging/unplugging the
device multiple times would intermittently show panics in completely
unrelated areas of the kernel.

8fe51725d8 [media] si2157: carry pointer to client instead of state in tuner_priv
Carry struct i2c_client pointer in tuner_priv. This driver is I2C driver,
which is represented as a struct i2c_client, so better to carry this top
level structure for each routine in order to unify things.
