[PATCH 6/6] ASoC: fsl_ssi: adjust set DAI format in AC'97 mode

[Maciej S. Szmigiero]

Adjust set DAI format function in fsl_ssi driver so it
doesn't fail and clears RXDIR in AC'97 mode.

I think it would be better to add another case for the other mode which
is supported (AC97) instead of using the default case.

Please fix this indention. Most of the driver is written with 2 tab
indention after a line break and the new policy seems to be to indent on
the opening bracket.

This is a switch of DAI clock masters and AC'97 is none of them:
while "case 0:" can be added this would be very similar to the current code.

Alternatively, the whole switch statement could be wrapped inside
"if (!fsl_ssi_is_ac97(ssi_private))" if that would be better
with regards to code style.

I looked at the wrong switch/case the DAIFMT_AC97 is actually used
but this patch is about the master clocks. It's fine then.

[PATCH 6/6 v2] ASoC: fsl_ssi: adjust set DAI format in AC'97 mode

[Maciej S. Szmigiero]

Adjust set DAI format function in fsl_ssi driver
so it doesn't fail and clears RXDIR in AC'97 mode.

Changes from v1: fix indentation to be consistent with rest
of the driver.

Inter version changelogs go after the --- as covered in
SubmittingPatches.

Please don't bury new patches in reply to old submissions, especially
not individual patches - it makes it hard to work out what's going on
and make sure that the most current version of everything is being
applied.  In order to avoid confusion I'm not going to look at these,
please resubmit as a new thread.

Please also try to thread your patch series together (git send-email can
do this for you) - it also helps people keep track of things.

Thanks for information.

In cases like this where only one patch of six patch series is updated
should other ones be resubmitted as well to keep the full patch series
together?

Yes, any unapplied patches should be resubmitted.
