As warned by smatch:
drivers/media/pci/tw5864/tw5864-core.c:160 tw5864_h264_isr() error: double lock 'irqsave:flags'
drivers/media/pci/tw5864/tw5864-core.c:174 tw5864_h264_isr() error: double unlock 'irqsave:flags'
Two different spinlocks are obtained, so having two calls is correct,
but second irqsave is superfluous, and using same "flags" variable is
just wrong.

The driver should not ignore errors while registering the I2C
bus, as this device can't even minimally work without the buses,
as it uses those buses internally to talk with the several IP
blocks inside the chip.

The cx231xx_get_i2c_adap() function should return the I2C
adapter that will be used to talk with a device. It should never
be NULL, as otherwise the driver will try to dereference a
null pointer.
We might instead fix the callers, but if this condition
ever happens, it is really a driver bug, because i2c_port
should always be a value from enum CX231XX_I2C_MASTER_PORT.
Found when checking the code due to this bug:
[ 39.769021] BUG: unable to handle kernel NULL pointer dereference at 0000000000000002

The number of the cx231xx REQ for GPIO register set/get are wrong.
They should follow what's there at cx231xx-pcb-cfg.h.
Noticed while checking the cx231xx parser at the v4l-utils.

If something bad happens when switching between digital
and analog mode, prints an error and outputs the returned code.
Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
This device uses GPIOs: 28 to switch between analog and
digital modes: on digital mode, it should be set to 1.
The code that sets it on analog mode is OK, but it misses
the logic that sets it on digital mode.

The cx231xx_set_agc_analog_digital_mux_select() callers
expect it to return 0 or an error. Returning a positive value
makes the first attempt to switch between analog/digital to fail.

With the current settings, only one channel locks properly.
That's likely because, when this driver was written, Brazil
were still using experimental transmissions.
Change it to reproduce the settings used by the newer drivers.
That makes it lock on other channels.
Tested with both PixelView SBTVD Hybrid (cx231xx-based) and
C3Tech Digital Duo HDTV/SDTV (em28xx-based) devices.

On this frontend, it takes a while to start output normal
TS data. That only happens on state S9. On S8, the TS output
is enabled, but it is not reliable enough.
However, the zigzag loop is too fast to let it sync.
As, on practical tests, the zigzag software loop doesn't
seem to be helping, but just slowing down the tuning, let's
switch to hardware algorithm, as the tuners used on such
devices are capable of work with frequency drifts without
any help from software.

Some messages have a hardcoded prefix; others not. Use the
