Revision 57be09c6e8747bf48704136d9e3f92bfb93f5725 authored by Navid Emamdoost on 02 October 2019, 03:46:07 UTC, committed by Alex Deucher on 02 October 2019, 17:58:33 UTC
In acp_hw_init there are some allocations that needs to be released in case of failure: 1- adev->acp.acp_genpd should be released if any allocation attemp for adev->acp.acp_cell, adev->acp.acp_res or i2s_pdata fails. 2- all of those allocations should be released if mfd_add_hotplug_devices or pm_genpd_add_device fail. 3- Release is needed in case of time out values expire.
