status is then polled e.g. via "dvb-fe-tool -m", i2c errors are printed
to the kernel log. If the last delsys was DVB-T/T2:

  cxd2841er: i2c wr failed=-5 addr=6c reg=00 len=1
  cxd2841er: i2c rd failed=-5 addr=6c reg=26

  cxd2841er: i2c rd failed=-5 addr=6c reg=49

This happens when read_status unconditionally calls into the
read_signal_strength() function which triggers the read_agc_gain_*()
functions, where these registered are polled.

This isn't a critical thing since when the demod is active again, no more
such errors are logged, however this might make users suspecting defects.

Fix this by requiring STATE_ACTIVE_* in priv->state. If it isn't in any
active state, additionally set the strength scale to NOT_AVAILABLE.

7 years agomedia: em28xx: Ignore errors while reading from eeprom

media: em28xx: Ignore errors while reading from eeprom

While testing support for Terratec H6 rev. 2, it was noticed
that reading from eeprom there causes a timeout error.

Apparently, this is due to the need of properly setting GPIOs.

In any case, the driver doesn't really require eeprom reading
to succeed, as this is currently used only for debug.

So, Ignore such errors.

[media] v4l2-ioctl/exynos: fix G/S_SELECTION's type handling

The type field in struct v4l2_selection is supposed to never use the
_MPLANE variants. E.g. if the driver supports V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE,
then userspace should still pass V4L2_BUF_TYPE_VIDEO_CAPTURE.

The reasons for this are lost in the mists of time, but it is really
annoying. In addition, the exynos drivers didn't follow this rule and
instead expected the _MPLANE type.

To fix that code is added to the v4l2 core that maps the _MPLANE buffer
types to their regular equivalents before calling the driver.

Effectively this allows for userspace to use either _MPLANE or the regular
buffer type. This keeps backwards compatibility while making things easier
for userspace.

Since drivers now never see the _MPLANE buffer types the exynos drivers
had to be adapted as well.

Commit e78902976150 ("i2c: sh_mobile: don't send a stop condition by

stop/start sequence between messages in a single transfer only when
explicitly requested with I2C_M_STOP.

This breaks the ov772x driver in the SH4 Migo-R board as the Omnivision
sensor uses the I2C-like SCCB protocol that doesn't support repeated
starts:

i2c-sh_mobile i2c-sh_mobile.0: Transfer request timed out
ov772x 0-0021: Product ID error 92:92

Fix it by marking the client as SCCB, forcing the emission of a
stop/start sequence between all messages.
As I2C_M_STOP requires the I2C adapter to support protocol mangling,
ensure that the I2C_FUNC_PROTOCOL_MANGLING functionality is available.

drivers/media/pci/ttpci/av7110_av.c. The structure contains a 'time_t',

incompatible ABI change for this ioctl.

As it turns out, neither of the drivers currently sets the timestamp

resolutions (no sub-second times). This means we can simply change
the structure definition to use a 'long' instead of 'time_t' and
remain compatible with all existing user space binaries when time_t
