Trivial fix to spelling mistake on calibration, make Self lowercase
and re-join multiple lined printk since checkpatch allows this

The Si2141 needs two distinct commands for powerup/reset, otherwise it
will not respond to chip revision requests. It also needs a firmware
to run properly.

'Reset' loop does not look correct. I tested it very many times and
it never repeated those commands. If problem, it tries to solve,
really occurs on some situations better solution should be find out.
There is another patch which does not have such hackish looking loop.
Lets change to it.

Now that %z is standartised in C99 there is no reason to support %Z.
Unlike %L it doesn't even make format strings smaller.
Use BUILD_BUG_ON in a couple ATM drivers.
In case anyone didn't notice lib/vsprintf.o is about half of SLUB which
is in my opinion is quite an achievement. Hopefully this patch inspires
someone else to trim vsprintf.c more.

I saw from ZyDAS ZD1301 sniffs it sets chip sleeping by using
REG_MISC_CTRL. That has very huge effect for power management, around
0.9W. Sleep is still disabled for all the old hardware just to avoid
possible regression as meaning of register bits are unknown.
I tested it also with some other devices and it seems to be working,
but I still consider it to be too risky to change it default.

The commit 8dfbcc4351a0 ("[media] xc2028: avoid use after free") tried
to address the reported use-after-free by clearing the reference.
However, it's clearing the wrong pointer; it sets NULL to
priv->ctrl.fname, but it's anyway overwritten by the next line
memcpy(&priv->ctrl, p, sizeof(priv->ctrl)).
OTOH, the actual code accessing the freed string is the strcmp() call
with priv->fname:
if (!firmware_name[0] && p->fname &&
priv->fname && strcmp(p->fname, priv->fname))
free_firmware(priv);
where priv->fname points to the previous file name, and this was
already freed by kfree().
For fixing the bug properly, this patch does the following:
- Keep the copy of firmware file name in only priv->fname,
priv->ctrl.fname isn't changed;
- The allocation is done only when the firmware gets loaded;
- The kfree() is called in free_firmware() commonly

While this patch sounded a good idea, unfortunately, it causes
bad dependencies, as drivers that would otherwise work without
the DVB core will now break:

So, we have to revert it.
Note: as the argument for the release ops changed from "int"
to "void", we needed to change it at the revert patch, to
avoid compilation issues like:

These are immutable. Making them "const" allows the compiler to move
them to the "rodata" section.
Note that cxd2841er_t_c_ops cannot be made "const", because

Due to the 80-cols restrictions, and latter due to checkpatch
warnings, several strings were broken into multiple lines. This
is not considered a good practice anymore, as it makes harder
to grep for strings at the source code.
As we're right now fixing other drivers due to KERN_CONT, we need
to be able to identify what printk strings don't end with a "\n".
It is a way easier to detect those if we don't break long lines.
So, join those continuation lines.
The patch was generated via the script below, and manually
adjusted if needed.
</script>
use Text::Tabs;
while (<>) {
if ($next ne "") {
$c=$_;
if ($c =~ /^\s+\"(.*)/) {
$c2=$1;
$next =~ s/\"\n$//;
$n = expand($next);
$funpos = index($n, '(');
$pos = index($c2, '",');
if ($funpos && $pos > 0) {
$s1 = substr $c2, 0, $pos + 2;
$s2 = ' ' x ($funpos + 1) . substr $c2, $pos + 2;
$s2 =~ s/^\s+//;
$s2 = ' ' x ($funpos + 1) . $s2 if ($s2 ne "");
print unexpand("$next$s1\n");
print unexpand("$s2\n") if ($s2 ne "");
} else {
print "$next$c2\n";
}
$next="";
next;
} else {
print $next;
}
$next="";
} else {
if (m/\"$/) {
if (!m/\\n\"$/) {
$next=$_;

Kernel source files need not include <linux/kconfig.h> explicitly
because the top Makefile forces to include it with:

This commit removes explicit includes except the following:
* arch/s390/include/asm/facilities_src.h
* tools/testing/radix-tree/linux/kernel.h
These two are used for host programs.

name to NULL after freeing it. While here, return an error if
the memory allocation fails.

The variable "rc" will be set to an appropriate value from a call of
the r820t_set_tv_standard() function.
Thus let us omit the explicit initialisation at the beginning.

This issue was detected by using the Coccinelle software.
1. Let us return directly if a call of the regmap_write() function failed.
2. Delete the jump label "err" then.
3. Return zero as a constant at the end.

A previous patch added a check if the firmware is too big, but it didn't
set the return error code with the right value.
[mchehab@osg.samsung.com: I ended by applying a v1 of Laura's patch, without
the proper return code. This patch contains the difference between v2 and v1 of
the Laura's "si2157: Bounds check firmware" patch]

The get_state()/set_state and the corresponding data types
(struct tuner_state and enum tuner_param) are old DVB interfaces
that came from the DVBv3 time.
Nowadays, set_params() provide a better way to set the tuner
and demod parameters. So, no need to keep those legacy stuff,
as all drivers that were using it got converted.
With this patch, all kABI elements at dvb_frontend.h are now
documented.

When reading the firmware and sending commands, the length
must be bounds checked to avoid overrunning the size of the command
buffer and smashing the stack if the firmware is not in the
expected format. Add the proper check.

Make the TV tuners menu visible when compile-testing, to allow
selecting additional drivers on top of the drivers that are already
automatically selected if MEDIA_SUBDRV_AUTOSELECT is enabled.
Without this, many drivers stay disabled during e.g. allmodconfig.

On alpha, gcc warns a log about signed/unsigned ballance, with
produces 3185 warnings. Ok, this is bogus, but it indicates that
the declaration at V4L2 side is not consistent with the one at
I2C.
With this trivial patch, the number of errors reduce to 2959
warnings. Still too much, but it is 7.1% less. So let's do it.
