Revision 21eb45db282317543ca46c821bbb8d5075e02cbe authored by Peter Ujfalusi on 19 August 2016, 06:34:24 UTC, committed by Mark Brown on 19 August 2016, 14:18:43 UTC
The dmic-codec was registered within the platform_driver's probe function, which can cause deferred probe to run in loops as reported and analyzed by Russell King. Use module_init/exit in the driver and handle the dmic-codec device registration and removal at that level instead of the platform_driver probe/remove.
