Subject: [PATCH] ASoC: WM8962: Let codec driver enable/disable its MCLK

From: Nicolin Chen <[email protected]>

WM8962 needs its MCLK when powerup in wm8962_resume(). Thus it's better
to control the MCLK in codec driver. Thus remove the clock enable in
machine dirver accordingly.

While at it, get rid of imx_wm8962_remove function since it is now
empty.

Subject: Re: [PATCH] ASoC: WM8962: Let codec driver enable/disable its MCLK

Hi,

Could you please revise the subject a bit? I forgot what's the
original one I submitted (internally) years ago. But the patch
is for imx-wm8962 instead of WM8962.

So please use
ASoC: fsl: imx-wm8962:
or at least
ASoC: imx-wm8962:

The change itself looks fine though.

Thanks
Nic

Hmm...it'd probably be better to let yourself be the author and remove
my signed-off here. Just got an email deliver failure since that email
address is apparently not available any more.

Hi Nic,

I will fix the prefix subject as suggested. Is it OK to use
your current email address for the signed-off-by tag?

The email address in the "From" would probably still remain that one,
which causes the problem.

I personally prefer that you resend it using your own and I could give
an Ack to it. It isn't really necessary to let me take the credit :)

the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
