Suspend/resume conditions can be very tricky. Add some info

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.

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.

It doesn't make sense to handle an IR code given before

int while suspending.

As the RC kthread can re-enable IR int, we should first
cancel the kthread and then disable IR int.

When the DVB code sets the frontend, it disables the IR
INT, probably due to some hardware bug, as there's no code
there at au8522 frontend that writes on register 0xe0.

Fixing it at au8522 code is hard, as it doesn't know if the
IR is enabled or disabled, and just restoring the value of
register 0xe0 could cause other nasty effects. So, better
to add a hack at au0828-input polling interval to enable int,
if disabled.

This driver receives ACPI notify events 0x80 when the sensor
detects a sudden move or a harsh vibration, as well as an
ACPI notify event 0x81 whenever the movement or vibration has
been stabilized.

Also provides sysfs entries to get/set the desired protection
level and reseting the HDD protection interface.

Some Toshiba models (most notably Qosmios) come with an
incomplete backlight method where the AML code doesn't
check for write or read commands and always returns
HCI_SUCCESS and the actual brightness (and in some
cases the max brightness), thus allowing the backlight
interface to be registered without write support.

This patch changes the set_lcd_brightness function,
checking the returned values for values greater than
zero to avoid registering a broken backlight interface.
