Provide access to the switch -by adding a 'non-stop-clocks' parameter to the audioinjector-addons -overlay. - -See: https://github.com/raspberrypi/linux/issues/2409 - -Signed-off-by: Phil Elwell <phil@raspberrypi.org> - -sound: Fixes for audioinjector-octo under 4.19 - -1.

Fix the diagnostics in an error path of the soundcard driver to -correctly identify the reason for the failure to load. - -3. Move the declaration of the clock node in the overlay outside -the I2C node to avoid warnings. - -4.
