[PATCH 1/2] Revert "ASoC: amd: acp: Set gpio_spkr_en to None for max speaker amplifer in machine driver"

[V sujith kumar Reddy]

RT1019 codec has two ways of controlling the en_spkr.
one way is controlling through gpio pin method the another way is through codec register update.

Now Speaker enable/disable is controlled  through register update in BIOS.
So this patch reverse gpio logic, which is no longer in use.

This reverts commit 7fa5c33d043160eba3be9fb8e21588dff2a467c7.

Surely this needs to be keyed off BIOS version otherwise we'll break
things for systems where the user hasn't updated their BIOS?

Please submit patches using subject lines reflecting the style for the
subsystem, this makes it easier for people to identify relevant patches.
Look at what existing commits in the area you're changing are doing and
make sure your subject lines visually resemble what they're doing.
There's no need to resubmit to fix this alone.

Hi Mark,

There is a mistake in commit message,Speaker enable and disable is 
controlled through rt1019 codec driver not through Bios.

Apologies for the inconvenience. We will update the commit message and 
resend.
