Subject: [PATCH v1 0/5] Improve decoder performance and fix critical bugs

The wave5 codec driver is a stateful encoder/decoder.
The following patches is for improving decoder performance and fix critical bugs

v4l2-compliance results:
========================

v4l2-compliance 1.26.1-5142, 64 bits, 64-bit time_t

Buffer ioctls:
                warn: v4l2-test-buffers.cpp(693): VIDIOC_CREATE_BUFS not supported
                warn: v4l2-test-buffers.cpp(693): VIDIOC_CREATE_BUFS not supported
        test VIDIOC_REQBUFS/CREATE_BUFS/QUERYBUF: OK
        test CREATE_BUFS maximum buffers: OK
        test VIDIOC_EXPBUF: OK
        test Requests: OK (Not Supported)

Total for wave5-dec device /dev/video0: 46, Succeeded: 46, Failed: 0, Warnings: 2 Total for wave5-enc device /dev/video1: 46, Succeeded: 46, Failed: 0, Warnings: 0

Fluster test results:
=====================

Running test suite JCT-VC-HEVC_V1 with decoder GStreamer-H.265-V4L2-Gst1.0 Using 1 parallel job(s)
Ran 132/147 tests successfully               in 67.220 secs

(1 test fails because of not supporting to parse multi frames, 1 test fails because of a missing frame and slight corruption,
 2 tests fail because of sizes which are incompatible with the IP, 11 tests fail because of unsupported 10 bit format)

Running test suite JVT-AVC_V1 with decoder GStreamer-H.264-V4L2-Gst1.0 Using 1 parallel job(s)
Ran 78/135 tests successfully               in 31.808 secs

(57 fail because the hardware is unable to decode  MBAFF / FMO / Field / Extended profile streams.)

Change since v0:
=================

* For [PATCH v1 3/5] media: chips-media: wave5: Improve performance of
  decoder
  - Fix Null reference while testing fluster for more than 2
    decoders
  - Fix timeout while testing fluster for multi instances
