This is just a cleanup, it doesn't change how the code works. These
are compound conditions and not bitwise operations so it should be &&

This patch replaces the previous one proposed in the thread "xc3028:
force reload of DTV7 firmware in VHF band with Zarlink demodulator",
at the linux-media@vger.kernel.org ML.
The problem is that the firmware DTV78 works fine in UHF band (8 MHz
bandwidth) but is not working at all in VHF band (7 MHz bandwidth).
Reading the comments inside the code, I figured out that the real
problem could be connected to the formula used to calculate the center
frequency offset in VHF band.
In fact, removing this adjustment fixes the problem:
if ((priv->cur_fw.type & DTV78) && freq < 470000000)
offset -= 500000;
This is coherent to what was implemented for the DTV7 firmware by an
Australian user:
if (priv->cur_fw.type & DTV7)
offset += 500000;
In the end, now the center frequency is the same for all firmwares
(DTV7, DTV8, DTV78) and doesn't depend on channel bandwidth.
The final code looks clean and simple, and there is no need for any
"magic" adjustment:
if (priv->cur_fw.type & DTV6)
offset = 1750000;
else /* DTV7 or DTV8 or DTV78 */
offset = 2750000;

Max8925 ldo status should be determined by two factors:
1. power up/down sequence selection(LDOCTL[4:2]).
2. i2c enable bit(LDOCTL[0]).
Max8925 ldo support two types of power up/down sequence:
1. flexible sequence(LDOCTL[4:2] = 0~6).
2. i2c sequence(LDOCTL[4:2] = 7).
With flexible sequence selected, the ldo is enabled during power up by default.
With i2c sequence selected, the ldo is controlled by the i2c enable bit(LDOCTL[0]).

It will be recalculated at __hists__output_resort, to take into account
filters possibly applied by the TUI, etc.
Since we do the percent math only for those entries that will appear on
the TUI instead of for _all_ the entries at decay time, updating it for
each sample makes the entries seem to decay faster when using the
navigation keys (since the screen will be refreshed), as we're not
coalescing the entries that are being batched to be merged at next
resort/decay time, but considering their periods.
Bug introduced in 743eb86.

The driver uses the pstate number from the status register as index in
its table of ACPI pstates (powernow_table). This is wrong as this is
not a 1-to-1 mapping.
For example we can have _PSS information to just utilize Pstate 0 and
Pstate 4, ie.
powernow-k8: Core Performance Boosting: on.
powernow-k8: 0 : pstate 0 (2200 MHz)
powernow-k8: 1 : pstate 4 (1400 MHz)
In this example the driver's powernow_table has just 2 entries. Using
the pstate number (4) as index into this table is just plain wrong.

During scaling up of cpu frequency, loops_per_jiffy
is updated upon invoking PRECHANGE notifier.
If setting to new frequency fails in cpufreq driver,
lpj is left at incorrect value.
Hence update lpj only if cpu frequency is changed,
i.e. upon invoking POSTCHANGE notifier.
Penalty would be that during time period between
changing cpu frequency & invocation of POSTCHANGE
notifier, udelay(x) may not gurantee minimal delay
of 'x' us for frequency scaling up operation.
Perhaps a better solution would be to define
CPUFREQ_ABORTCHANGE & handle accordingly, but then
it would be more intrusive (using ABORTCHANGE may
help drivers also; if any has registered notifier
and expect POST for a PRECHANGE, their needs can
be taken care using ABORT)

CPU frequency is guranteed to be changed on notifier callback with
CPUFREQ_POSTCHANGE. Notifier callback with CPUFREQ_PRECHANGE does
not gurantee a change in frequency; after it, if cpufreq driver is
unable to change CPU to new frequency. This results in wrong
information being fed to user (if setting CPU frequency fails)
upon doing like,
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed
Hence in userspace governer update cpu_cur_freq only if notifier
has been called with POSTCHANGE.

When reading RAID5 files, in rare cases, we calculated too
few sg segments. There should be two extra for the beginning

Also "too few sg segments" should not be a BUG_ON there is
all the mechanics in place to handle it, as a short read.
So just return -ENOMEM and the rest of the code will gracefully
split the IO.

We must split exofs/Kconfig in two. The ore one is always included.
And the exofs one is left in it's old place in the menu.

Bail out if dvb_net_init encounters an error (for example an
out-of-memory condition), now that it reports them.

Avoid some repetition by adopting the usual "goto err" idiom for error
handling.

Repeating the same cleanup code in each error handling path makes life
unnecessarily difficult for reviewers, who much check each instance of
the same copy+pasted code separately. A "goto" to the end of the
function is more maintainable and conveys the intent more clearly.
While we're touching this code, also lift some assignments from "if"
conditionals for simplicity.
No functional change intended.

videobuf_dvb_register_bus relies on dvb_net_init to set dvbnet->dvbdev
on success, but ever since commit fcc8e7d8c0e2 ("dvb_net: Simplify the
code if DVB NET is not defined"), ->dvbdev is left unset when
networking support is disabled. Therefore in such configurations
videobuf_dvb_register_bus always returns failure, tripping
little-tested error handling paths and preventing the device from
being initialized and used.
Now that dvb_net_init returns a nonzero value on error, we can use
that as a more reliable error indication. Do so.
Now your card be used with CONFIG_DVB_NET=n, and the kernel will pass
on a more useful error code describing what happened when
CONFIG_DVB_NET=y but dvb_net_init fails due to resource exhaustion.

dvb_net_init unconditionally returns 0. Callers such as
videobuf_dvb_register_frontend examine dvbnet->dvbdev instead of the
return value to tell whether the operation succeeded. If it has been
set to a valid pointer, success; if it was left equal to NULL,
failure.
Alas, there is an edge case where that logic does not work as well:
when network support has been compiled out (CONFIG_DVB_NET=n), we want
dvb_net_init and related operations to behave as no-ops and always
succeed, but there is no appropriate value to which to set dvb->dvbdev
to indicate this.
Let dvb_net_init return a meaningful error code, as preparation for
adapting callers to look at that instead.
The only immediate impact of this patch should be to make the few
callers that already check for an error code from dvb_net_init behave
a little more sensibly when it fails.

New driver for the hardware watchdog timer on VIA chipsets.
This driver uses the new watchdog framework.
PnP must be enabled in BIOS to get full control of watchdog registers.
The timer code has been added by Wim Van Sebroeck.
Tested on a Artigo A1100, VX855 chipset.
