This patch series adds the listed bug fixes that have been missing
in upstream fastRPC driver.
- Fix DSP capabilities request.
- Fix issues in audio daemon attach operation.
- Restrict untrusted app to attach to privilegeded PD.

Changes in v2:
- Added separate patch to add newlines in dev_err.
- Added a bug fix in fastrpc capability function.
- Added a new patch to save and restore interrupted context.
- Fixed config dependency for PDR support.

Changes in v3:
- Dropped interrupted context patch.
- Splitted few of the bug fix patches.
- Added Fixes tag wherever applicable.
- Updated proper commit message for few of the patches.

Changes in v4:
- Dropped untrusted process and system unsigned PD patches.
- Updated proper commit message for few of the patches.
- Splitted patches in more meaningful way.
- Added helped functions for fastrpc_req_mmap.

Changes in v5:

  series. These patches will be shared separately as a new patch series.
- Changed patch series subject as this series is no longer carrying any
  new feature changes.
