Re: [PATCH 10/11] ASoC: topology: Use unload() op directly

This is a convoluted explanation, and the code does not support this
last sentence.

There is no existing dobj 'function pointer', it's added by this patch ....

... here.

I don't see the gain, sorry.

Edit: This removal only makes sense with the patch 11 added, where the
same function can be used to remove multiple types of control.

Please revisit the commit message here and explain the intent, otherwise
this change in isolation isn't really useful.

Please clarify that this is not a cleanup removing duplicated code
that's been there forever, it's become useless as a result of the
previous patch.

[PATCH 01/11] ASoC: topology: Properly access value coming from topology file

[Amadeusz Sławiński]

When accessing values coming from topology, le32_to_cpu should be used.
One of recent commits missed that.

[PATCH 07/11] ASoC: topology: Pass correct pointer instead of casting

[Amadeusz Sławiński]

Instead of passing address of structure, the containg structure is
casted to target structure. While it works - the expected structure is
the first field of containing one - it is bad practice, fix this by
passing pointer to structure field.

[PATCH 09/11] ASoC: Topology: Remove unnecessary check for EOF

[Amadeusz Sławiński]

Caller already checks if hdr_pos is behind EOF, before calling
soc_tplg_valid_header(), so there is no need to recheck it again. This
also allows to remove behaviour of return 0 - forcing the caller to
break out of while loop.

Generic dynamic object (struct snd_soc_dobj) needs pointer to unload
function, however, instead of using function pointer to point at it
directly it points to all topology operations. Change code to use the
function pointer instead.

 LGTM, thanks, Amadeusz!

There is no dependency on previous patch - it is just order I've send 
them in - those functions have same implementation in current code.

Not following, sorry. What is this addition in patch 10?

diff --git a/include/sound/soc-topology.h b/include/sound/soc-topology.h

+	int (*unload)(struct snd_soc_component *comp, struct snd_soc_dobj *dobj);

That's not in 'current code', is it? How is this not a dependency?

It only depends on it because of order I did changes in, but there is 
really no dependency here. I will send v2 with reversed order.
