commit 9bf03a0cbd80a256bc1e1c4bcc80bc2b06b8b2b9 upstream.
The init counter is not decremented on initialisation errors, which prevents retrying initialisation and can lead to the runtime suspend callback attempting to disable resources that have never been enabled.
Add the missing decrement on initialisation errors so that the counter reflects the state of the device.
