ASoC: wcd9xxx: Disable current source in error scenarios

Sometimes during removal, fake electrical removal interrupt
can also get generated. In that case, current source needs
to be disabled after a round of DCE measurements. Otherwise,
next time when the plug is re-inserted, measurements can go
wrong and hence plug type can be wrongly detected.

Revert "asoc: msm: Check headset insertion for consistency"

 * Superseded by the next patch, which also eliminates the long delay
   when certain types of headsets are inserted.

This reverts commit 7d9a3bf12051d48ee7290a865d25c97654d080f4.

ASoC: wcd9xxx: Continue polling for Unsupported plug types

Sometimes slow insertion of headphone could lead to
detection of unsupported plug types. In these cases,
continue polling so that headphone can be detected
once it is fully inserted.

ASoC: msm: qdsp6v2: set stream volume before starting it

Volume gains for a stream should be set before sending
RUN command to DSP. This will avoid any glitch in audio
which might occur because of rapid change in volume level
while setting up the appropriate volume for the stream.

msm: mdss: fix pixel extension validation on decimation

When decimating and if chroma is to be downsampled, hw doesn't decimate
for first step. This needs to be considered as part of the pixel
extension values validation.

msm: mdss: fix check for bwc and decimation

Decimation flag is not sufficient to prevent decimation from being
enabled. Instead check that decimation values are also not set.

msm: mdss: reduce waiting time before turn off mdp clock

Vsync happens at every 16.6 ms. Currently it waits for
6 vsyncs (100 ms) time before turning off mdp clock if
there is no new frame update. During suspend procedure,
change it to 1 so that mdp clock is turned off 1 vsync
after kickoff has completed if there is kickoff pending.
Otherwise mdp clock is turned off at next vsync.

mdss: mdp: release file node before process node when open fail

Releasing file node after process node causes the kernel
panic because process node is already freed. Correct order
to release nodes should be file node followed by process node
when PM API fails.

msm: mdss: free ion memory after panel is blanked

Frame buffer memory could still be fetched until panel is completely
blanked, in order to avoid potential page faults by unmapping early,
move unmapping of this memory until after panel is blanked.
