media: cec-notifier: Get notifier by device and connector name

2018-07-13T07:44:16+00:00

In non device-tree world, we can need to get the notifier by the driver
name directly and eventually defer probe if not yet created.

This patch adds a variant of the get function by using the device name
instead and will not create a notifier if not yet created.

But the i915 driver exposes at least 2 HDMI connectors, this patch also
adds the possibility to add a connector name tied to the notifier device
to form a tuple and associate different CEC controllers for each HDMI
connectors.

media: cec: fix wrong tx/rx_status values when canceling a msg

2018-05-28T20:25:25+00:00

When a message was canceled it could return tx_status with
both OK and MAX_RETRIES set, which is illegal.

If a canceled message was waiting for a reply, then rx_status
wasn't updated, so set that as well.

media: cec-pin-error-inj: avoid a false-positive Spectre detection

2018-05-28T20:11:17+00:00

The current logic makes Smatch to false-detect a Spectre variant 1
vulnerability. The problem is that it initializes an u32 indirectly
from user space input.

After trying to write a fixup, after a while I realized that, in
practice, this shouldn't be a problem, as an u32 is initialized
from u8, but it took some time to discover it.

So, do some code cleanup to make it clearer for both humans
and machines about the valid range for "op".

Fix this warning:

media: rc: per-protocol repeat period and minimum keyup timer

2018-04-20T13:16:55+00:00

Each IR protocol has its own repeat period. We can minimise the keyup
timer to be the protocol period + IR timeout. This makes keys less
"sticky" and makes IR more reactive and nicer to use.

This feature was previously attempted in commit d57ea877af38 ("media: rc:
per-protocol repeat period"), but that did not take the IR timeout into
account, and had to be reverted.

media: cec: set ev rather than v with CEC_PIN_EVENT_FL_DROPPED bit

2018-04-20T12:37:35+00:00

Setting v with the CEC_PIN_EVENT_FL_DROPPED is incorrect, instead
ev should be set with this bit. Fix this.

drivers/media/cec/cec-pin-error-inj.c:231
cec_pin_error_inj_parse_line() error: uninitialized symbol 'pos'.

The tx-add-bytes command didn't check for the presence of an argument, and
also didn't check that it was > 0.

This should fix this error.

media: cec-pin: Fixed ktime_t to ns conversion

2018-04-04T10:12:52+00:00

Older Kernels use a struct for ktime_t, which requires the conversion
function ktime_to_ns to be used on some places. With this patch it will
compile now also for older Kernel versions.

media: cec-core: fix a bug at cec_error_inj_write()

2018-03-23T12:37:22+00:00

If the adapter doesn't have error_inj_parse_line() ops, the
write() logic won't return -EINVAL, but, instead, it will keep
looping, because "count" is a non-negative number.
