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

2021-09-18T11:43:46+00:00

[ Upstream commit 38367073c796a37a61549b1f66a71b3adb03802d ] tegra_cec_probe() and tegra_cec_resume() ignored possible errors of clk_prepare_enable(). The patch fixes this.

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.

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.
