Don't use ccflags, just use the correct MODULE_EXPORT_NS() tag instead.
The documentation [1] states
"
Defining namespaces for all symbols of a subsystem can be very verbose and
may become hard to maintain. Therefore a default define
(DEFAULT_SYMBOL_NAMESPACE) is been provided, that, if set, will become the
default for all EXPORT_SYMBOL() and EXPORT_SYMBOL_GPL() macro expansions
that do not specify a namespace.
"
If the ccflags option is not supported or no longer desired, it'd be worth
updating the documentation for dummies like me. I took the wording as a hint
to avoid using MODULE_EXPORT_NS.
It's supported, and works just fine. It's just that you really don't
have a ton of exports, right? What's wrong with manually marking them?
I don't see a MODULE_EXPORT_NS so we'd have to change every single
EXPORT_SYMBOL to EXPORT_SYMBOL_NS.
If we are talking about adding the namespaces just about the top-level
functions used by Intel, yes we have less than 10 and since they were
renamed it's no big deal.
But if we want to use this namespace for lower-level components of the
SoundWire code, we have 17 exports in cadence_master.c and more than 27
for the core parts. With the Makefile changes shared last week you'd
have 3 changes, I find it more manageable but it's true that the
information would be split with the IMPORT_NS in the code and the
namespace definition in the Makefile.
And "SDW_CORE" is odd, "SOUNDWIRE" instead?
'sdw' is the prefix used everywhere for SoundWire symbols.
Ok, I guess that ship has sailed :(
we can still use SOUNDWIRE for the namespaces, that'd be fine. you're
right to call us on acronyms, it's a bad habit.
