MaxLinear 692 is a combo demod/tuner which has ATSC and QAM
capabilities. Only ATSC is currently advertised via DVB
properties. QAM still has issues.
Confirmed working on both big and little endian. Big
endian verified on PowerPC Mac mini.

In preparation to enable -Wimplicit-fallthrough for Clang, fix multiple

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: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.

conversion, plus a float-point math. While gcc should be

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,

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.

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.

Neither the PCI skeleton nor the DVB dummy driver are real
drivers. They're there just as an example for a driver
writter.
Distros should not enable those drivers. So, hide them if
MEDIA_TEST_SUPPORT is not selected.

The shifting of buf[3] by 24 bits to the left will be promoted to
a 32 bit signed int and then sign-extended to an unsigned long. In
the unlikely event that the the top bit of buf[3] is set then all
then all the upper bits end up as also being set because of
the sign-extension and this affect the ev->post_bit_error sum.
Fix this by using the temporary u32 variable bit_error to avoid
the sign-extension promotion. This also removes the need to do the
computation twice.
