Subject: [PATCH 426/782] sound: Fixes for audioinjector-octo under 4.19
|
|
|
|
1. Move the DT alias declaration to the I2C shim in the cases
|
|
where the shim is enabled. This works around a problem caused by a
|
|
4.19 commit [1] that generates DT/OF uevents for I2C drivers.
|
|
|
|
2. 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. Sort the overlay nodes so that dependencies are only to earlier
|
|
fragments, in an attempt to get runtime dtoverlay application to
|
|
work (it still doesn't...)
|
