[media] mantis_pci: remove asm/pgtable.h include

2011-03-03T13:15:35+00:00

mantis_pci.c is including asm/pgtable.h and it's leading to a build failure on
arm. It has been noticed here :

https://buildd.debian.org/fetch.cgi?pkg=linux-2.6&arch=armel&ver=2.6.38~rc6-1~experimental.1&stamp=1298430952&file=log&as=raw

As this header doesn't seem to be used, I'm removing it. I've build tested it
with arm and x86.

[media] DiB7000M: add pid filtering

2011-03-02T16:45:12+00:00

This patch adds the pid filtering for the dib7000M demod. It also
corrects the pid filtering for the dib7700 based board. It should
prevent an oops, when using dib7700p based board.

kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT

2011-01-21T01:02:05+00:00

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

[media] firedtv: fix remote control with newer Xorg evdev

2011-01-19T13:45:59+00:00

After a recent update of xf86-input-evdev and xorg-server, I noticed
that X11 applications did not receive keypresses from the FireDTV
infrared remote control anymore.  Instead, the Xorg log featured lots of

    "FireDTV remote control: dropping event due to full queue!"

exclamations.  The Linux console did not have an issue with the
FireDTV's RC though.

The fix is to insert EV_SYN events after the key-down/-up events.

[media] frontends/ix2505v: Remember to free allocated memory in failure path

2011-01-19T13:45:44+00:00

We may leak the storage allocated to 'state' in
drivers/media/dvb/frontends/ix2505v.c::ix2505v_attach() on error, as
it is too early to be able to call ix2505v_release().

This patch makes sure we free the allocated memory in the failure case.

[media] mb86a20s: Be sure that device is initialized before starting DVB

2011-01-19T13:45:25+00:00

Due to a hard to track bug between tda829x/tda18271/saa7134, tda829x
wants to go to analog mode during DVB initialization, causing some
I2C errors.

The analog failure doesn't cause any harm, as the device were already
properly initialized in analog mode. However, the failure at the digital
mode causes the frontend mb86a20s to not initialize. Fortunately, at
least on my tests, it was possible to detect that the device is a
mb86a20s before the failure.

What happens is that tda8290 is a very bad boy: during DVB setup, it
keeps insisting to call tda18271 analog_set_params, that calls
tune_agc code. The tune_agc code calls saa7134 driver, changing the
value of GPIO 27, switching from digital to analog mode and disabling
the access to mb86a20s, as, on Kworld SBTVD, the same GPIO used
to switch the hardware AGC mode seems to be used to enable the I2C
switch that allows access to the frontend (mb86a20s).

So, a call to analog_set_params ultimately disables the access to
the frontend, and causes a failure at the init frontend logic.

This patch is a workaround for this issue: it simply checks if the
frontend init had any failure. If so, it will init the frontend when
some DTV application will try to set DVB mode.

Even being a hack for Kworld SBTVD to work, and assumning that we could
teach tda8290 to be a good boy, this is actually an improvement at the
frontend driver, as it will be more reliable to initialization failures.
