V4L/DVB: ir-core: Fix null dereferences in the protocols sysfs interface

2010-09-30T10:18:37+00:00

For some cards, ir_dev->props and ir_dev->raw are both NULL. These cards are
using built-in IR decoding instead of raw, and can't easily be made to switch
protocols.

So upon reading /sys/class/rc/rc?/protocols on such a card, return 'builtin' as
the supported and enabled protocol. Return -EINVAL on any attempts to change
the protocol. And most important of all, don't crash.

V4L/DVB: IR: fix keys beeing stuck down forever

2010-09-28T01:21:55+00:00

The logic in ir_timer_keyup was inverted.

In case that values aren't equal,
the meaning of the time_is_after_eq_jiffies(ir->keyup_jiffies) is that
ir->keyup_jiffies is after the the jiffies or equally that
that jiffies are before the the ir->keyup_jiffies which is
exactly the situation we want to avoid (that the timeout is in the future)
Confusing Eh?

V4L/DVB: rc-core: increase repeat time

2010-09-28T01:21:53+00:00

As reported by Anton Blanchard , double IR events on
2.6.36-rc2 and a DViCO FusionHDTV DVB-T Dual Express are happening:

[ 1351.032084] ir_keydown: i2c IR (FusionHDTV): key down event, key 0x0067, scancode 0x0051
[ 1351.281284] ir_keyup: keyup key 0x0067

ie one key down event and one key up event 250ms later.

So, we need to increase the repeat timeout, to avoid this bug to hit.

As we're doing it at core, this fix is not needed anymore at dib0700 driver.

Those breakages seem to be caused by two bad things at IR_CORE Kconfig:

1) cx23885 is using select for IR_CORE;
2) the dvb-usb and sms dependency for IR_CORE were missing.

While here, allow users to un-select IR.

V4L/DVB: IR keymap: Add print button for HP OEM version of MCE remote

2010-08-09T02:43:00+00:00

This patch adds a defintion for the "Print" button found on HP OEM
versions of the MCE remote.  All of the other keys found on the HP OEM
version of the remote match the other keys as already defined.

Because, who doesn't need "remote printing", while one is sitting on the
couch across from one's PC? ;)
