media: cec: copy sequence field for the reply

2021-12-01T08:04:41+00:00

commit 13cbaa4c2b7bf9f8285e1164d005dbf08244ecd5 upstream. When the reply for a non-blocking transmit arrives, the sequence field for that reply was never filled in, so userspace would have no way of associating the reply to the original transmit. Copy the sequence field to ensure that this is now possible.

media: tegra-cec: Handle errors of clk_prepare_enable()

2021-08-04T12:43:52+00:00

tegra_cec_probe() and tegra_cec_resume() ignored possible errors of clk_prepare_enable(). The patch fixes this. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by: Evgeny Novikov Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: cec-pin: rename timer overrun variables

2021-08-04T12:43:52+00:00

The cec pin timer overruns are measured in microseconds, but the variable names include the millisecond symbol "ms". To avoid confusion, replace "ms" with "us" in the variable names and printed status message. Signed-off-by: Deborah Brouwer Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: platform: stm32: unprepare clocks at handling errors in probe

2021-07-22T12:01:55+00:00

stm32_cec_probe() did not unprepare clocks on error handling paths. The patch fixes that. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by: Evgeny Novikov Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: s5p: fix pm_runtime_get_sync() usage count

2021-05-10T09:36:33+00:00

The pm_runtime_get_sync() internally increments the dev->power.usage_count without decrementing it, even on errors. Replace it by the new pm_runtime_resume_and_get(), introduced by: commit dd8088d5a896 ("PM: runtime: Add pm_runtime_resume_and_get to deal with usage counter") in order to properly decrement the usage counter, avoiding a potential PM usage counter leak. While here, check if the PM runtime error was caught at s5p_cec_adap_enable().

media: s5p_cec: decrement usage count if disabled

2021-05-10T09:36:33+00:00

There's a bug at s5p_cec_adap_enable(): if called to disable the device, it should call pm_runtime_put() instead of pm_runtime_disable(), as the goal here is to decrement the usage_count and not to disable PM runtime.

media: cec/core: clarify rx-arb-lost usage message

2021-04-06T14:08:38+00:00

The rx-arb-lost error injection command only works with set to 'any'. Explicitly say so in the usage message. Also use [] to indicate that the argument is optional. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: cec/core/cec-notifier: use IS_REACHABLE(CONFIG_I2C)

2021-03-22T09:24:44+00:00

If CONFIG_I2C=m and CONFIG_CEC_CORE=y then of_find_i2c_device_by_node() is not reachable. So use IS_REACHABLE instead of IS_ENABLED.

media: cec-notifier: also search for HDMI devices on I2C

2021-03-11T10:59:44+00:00

Currently the cec_notifier_parse_hdmi_phandle function can only be used if the HDMI device associated with the CEC device is a platform device. Extend the function to cover I2C devices as well, as there do exist some I2C HDMI devices which don't handle CEC internally and need an external CEC adapter.
