The attribution of dev->boards occured too late, which
would couse an OOPS in media controller registration.

au0828 IR stop and poll routines continue to access device
while usb disconnect is in progress. There is small window
between device disconnect and usb interface is set to null.
This results in filling the log with several of the following
error messages. Fix it to detect device disconnect condition
and avoid device access.

Suspend/resume conditions can be very tricky. Add some info
printk's to help tracking what's happening there.
Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
Instead of using printk(KERN_foo, use pr_foo() macros.
No functional changes.
Note: we should do the same for dprintk(), but that would
require to remove the dprintk levels. So, for now, let's
not touch on it.

No timers should be enabled during suspend. So,
stop them. At resume time, we should do the proper
initialization for it to keep working.

The scheduled work should be cancelled during suspend.
At resume time, we need to set the frontend again. So,
add such logic to the driver.

At resume, we should restore the register contents. So,
reenable the bridge and GPIO settings.

Trying to make au0828 to suspend can do very bad things, as
the polling Kthread is not handled. We should disable it
during suspend, only re-enabling it at resume.
Still, analog and digital TV won't work, as we don't reinit
the settings at resume, but at least it won't hang.

HVR-950Q uses an I2C remote controller at address 0x47 (7-bits
notation). Add support for it.

Added command line parameter preallocate_big_buffers so that the digital
transfer buffers can be allocated when the driver is registered. They
do not have to be allocated every time a feed is started.

The driver crashed when the device was disconnected while an application
still had a device node open. Fixed by using the release() callback of struct
v4l2_device.

This patch removes the dependendency of VIDEO_AU0828 on VIDEO_V4L2 by
creating a new Kconfig option, VIDEO_AU0828_V4L2, which enables analog
video capture support and depends on VIDEO_V4L2 itself.
With VIDEO_AU0828_V4L2 disabled, the driver will only support digital
television and will not depend on the v4l2-core. With VIDEO_AU0828_V4L2
enabled, the driver will be built with the analog v4l2 support included.
By default, the VIDEO_AU0828_V4L2 option will be set to Y, so as to
preserve the original behavior.
