Hi,
Something that's been bugging me over the years is how some drivers have
had to adopt file-scoped variables to pass data into something like the
syscore operations. This is often harmless, but usually leads to drivers
not being able to deal with multiple instances, or additional frameworks
or data structures needing to be created to handle multiple instances.
This series proposes to "objectify" struct syscore_ops by passing a
pointer to struct syscore_ops to the syscore callbacks. Implementations
of these callbacks can then make use of container_of() to get access to
contextual data that struct syscore_ops was embedded in. This elegantly
avoids the need for file-scoped, singleton variables, by tying syscore
to individual instances.
Patch 1 contains the bulk of these changes. It's fairly intrusive
because it does the conversion of the function signature all in one
patch. An alternative would've been to introduce new callbacks such that
these changes could be staged in. However, the amount of changes here
are not quite numerous enough to justify that, in my opinion, and
syscore isn't very frequently used, so the risk of another user getting
added while this is merged is rather small. All in all I think merging
this in one go is the simplest way.
Patches 2-7 are conversions of some existing drivers to take advantage
of this new parameter and tie the code to per-instance data.
Given that the recipient list for this is huge, I'm limiting this to
Greg (because it's at the core a... core change) and a set of larger
lists for architectures and subsystems that are impacted.
Thanks,
Thierry

Pass a pointer to the syscore_ops structure that was registered to the
callbacks. This enables callbacks to act on instance data (syscore_ops
can be embedded into other structures, and driver-specific data can be
obtained using container_of()) rather than the current practice of
relying on global variables.
