From 2782c393e16d9baf64bc93544e053e8ac97fdab7 Mon Sep 17 00:00:00 2001 From: Ekansh Gupta Date: Tue, 11 Jun 2024 16:04:37 +0530 Subject: misc: fastrpc: Avoid updating PD type for capability request When user is requesting for DSP capability, the process pd type is getting updated to USER_PD which is incorrect as DSP will assume the process which is making the request is a user PD and this will never get updated back to the original value. The actual PD type should not be updated for capability request and it should be serviced by the respective PD on DSP side. Don't change process's PD type for DSP capability request.
