This reverts commit 467a37fba93f2b4fe3ab597ff6a517b22b566882.
Because of recent interactions with developers from @umn.edu, all
commits from them have been recently re-reviewed to ensure if they were
correct or not.
Upon review, this commit was found to be incorrect for the reasons
below, so it must be reverted. It will be fixed up "correctly" in a
later kernel change.
This commit is not properly checking for an error at all, so if a
read succeeds from this device, it will error out.

Fix the following coccinelle report:

Code was enclosed with #if 0 and thus this variable was not needed.

since the function doesn't do anything. A comment was left at its

Constify a number of static structs that were not modified. In order to
be able to do that, const input arguments to a couple of functions that
not modify their argument. This allows the compiler to put them in
read-only memory, resulting in about 6k memory being read-only, and the
resulting module is 400 bytes smaller.

The usage of castings and float point when checking for
the setup based at the symbol_rate cause those warnings
with smatch:

drivers/media/dvb-frontends/tda10021.c:155 tda10021_set_symbolrate() warn: unsigned 'symbolrate' is never less than zero.

drivers/media/dvb-frontends/tda10021.c:159 tda10021_set_symbolrate() warn: unsigned 'symbolrate' is never less than zero.
While the code should work with gcc, as it will evaluate the
values into a constant before compiling, other compilers
could do otherwise. So, get rid of float pointing math on it,
avoiding the need of doing typecasts.
While here, cleanup some coding style issues at the related
code.

Using uninitialized_var() is dangerous as it papers over real bugs[1]
(or can in the future), and suppresses unrelated compiler warnings
(e.g. "unused variable"). If the compiler thinks it is uninitialized,
either simply initialize the variable or make compiler changes.
In preparation for removing[2] the[3] macro[4], remove all remaining
needless uses with the following script:
git grep '\buninitialized_var\b' | cut -d: -f1 | sort -u | \
xargs perl -pi -e \
's/\buninitialized_var\(([^\)]+)\)/\1/g;
s:\s*/\* (GCC be quiet|to make compiler happy) \*/$::g;'
drivers/video/fbdev/riva/riva_hw.c was manually tweaked to avoid
pathological white-space.
No outstanding warnings were found building allmodconfig with GCC 9.3.0
for x86_64, i386, arm64, arm, powerpc, powerpc64le, s390x, mips, sparc64,

Message logged by 'dev_xxx()' or 'pr_xxx()' should end with a '\n'.
While at it, change the log level from 'err' to 'debug'.

Using select for DVB_CORE doesn't work, as reported by
Randy:
CONFIG_I2C=m
CONFIG_DVB_CORE=y
ld: drivers/media/dvb-core/dvbdev.o: in function `dvb_module_probe':
dvbdev.c:(.text+0xf92): undefined reference to `i2c_new_client_device'
ld: dvbdev.c:(.text+0xffb): undefined reference to `i2c_unregister_device'
ld: drivers/media/dvb-core/dvbdev.o: in function `dvb_module_release':
dvbdev.c:(.text+0x107d): undefined reference to `i2c_unregister_device'
The problem is actually caused by the dummy frontend driver,
which uses select, and it is missing an I2C dependency:
WARNING: unmet direct dependencies detected for DVB_CORE
Depends on [m]: MEDIA_SUPPORT [=y] && MEDIA_DIGITAL_TV_SUPPORT [=y] && (I2C [=m] || I2C [=m]=n)
Selected by [y]:
- DVB_DUMMY_FE [=y] && MEDIA_SUPPORT [=y] && MEDIA_TEST_SUPPORT [=y]
As this is the only frontend driver using "select DVB_CORE",
change it do depends on DVB_CORE.

There are *lots* of I2C ancillary drivers. While we're using
comments to group them, all options appear at the same menu.
It should be a lot clearer to group them into sub-menus, with
may help people to go directly to the driver(s) he's needing
to enable.

Those documents don't really describe the driver API.
Instead, they contain development-specific information.
Yet, as the main index file describes the content of it as:
"how specific kernel subsystems work
from the point of view of a kernel developer"
It seems to be the better fit.

Most of media Kconfig/Makefile files already has SPDX,
but there are a few ones still missing. Add it to them.

There are some long-time mistakes related to build test
drivers, with regards to depends on/select. Also, as we
now want to build any test driver without needing to
enable anything else, change the logic in order to properly
filter them.
Please notice that the PCI skeleton is somewhat an
exception, as it requires to select *both* SAMPLES and
MEDIA_TEST_SUPPORT. I almost changed it to be either one,
but decided to keep it as-is, as this is something that
we don't really need to be included on any distribution.
The only reason for someone to build it is for COMPILE_TEST
purposes.
