Issue Description

realsense-viewer logs errors whenever it starts up. The viewer works, but I don't understand if it is somehow impaired due to these errors;

Those are the errors at startup. These errors are logged when I turn on an off the depth, rgb and imu streams.

Hi @Ezward Most of these are due to lacking kernel patches (specifically all of the warnings). Not sure what is the nature of the errors. For D400 cameras on kernel 5.3 not having kernel patches have some small negative effects, like not having most accurate time-stamping and synchronization. We are hard at work adding support for 5.x kernel versions. If you follow Linux installation instructions and apply scripts from the development branch, you should be able to get everything working. Also, librealsense2-dkms package was either already published or will be shortly for the 5.3 version.

I'll wait for the 5.3 kernel support.
