We do not check dev for null in any of the other functions. If it
was actually null then we would also already have got a null pointer
dereference earlier in the function.
Or it leads to interesting errors when adding fields to the table
of supported devices.

This should never happen on the Etekcity Scroll Alpha, but we might end
up in a situation where this is required.

Still a mystery of what it is. Though I know how to get/set it, so let's
make it public until somebody claims what it is.

Otherwise the symbol leak test won't recognize it and fails. It's not worth
hacking up that test to avoid implementing those few, so just write them out
instead.

etekcity suppports macros already, the other two don't. hidpp10 doesn't
support any write stuff but let's claim we do anyway.
The driver hook for this isn't ideal, read_button is called during init but
we should set all this up during probe and then use read_button exclusively to
update the button, not set the capabilities as well.

This is the physical description of the button, so there's a distinct
difference between the two, even when the logical action is the same.

Move the struct declarations together (and move ratbag_device to the ratbag
device page), have the defgroup tags at the top of the file.

profile was already dereferenced earlier in the function and cannot
be null anyway from the current callers of the function.

If we goto err early then both dev and drv_data will contain
garbage values. We free one and dereference the other. Let's
null them and add proper checks.

It is a common pattern to have:
ratbag_resolution_init(...)
profile->resolution.modes[i].xxx = yyy;
ratbag_resolution_set_cap(&profile->resolution.modes[i], zzz)
So instead of dealing with the internal fields of profile/resolution/modes,
just return the resolution that has been initialized.

In the end, we just ignore the sensitivity setting.
On the Etekcity, it looks like it is ignored by the mouse, or
maybe the Windows software just messes things up and should
not update the per-axis dpi when playing with sensitivity.

Currently only the hooks for x/y resolution, the rest is unimplemented. Also
the etekcity driver needs an update here.

No functional changes, this is in preparation for the future to make
replacing bits a bit easier - hopefully we only have to change the macro and
not every element then.

The one mode may be disabled and not configurable, but it's still more

Long-term we should have probe() and read_profile(), the latter of which
should read each profile and fill in _all_ information.

And the same for set_active_profile -> set_active. This API is more reliable,
the previous incarnation required the client to compare pointer values.

When we read the profiles, we need to know the capabilities of the device.
If the device has not been enumerated, then we are screwed.

given that we create all the buttons and profiles during probe(), there
is no need to re-probe for it every time we access it.
Right now, this works because only ratbag-command uses the library and
is a one shot program.
In the future, we should also read the events to detect changes in the
configuration if the user can use physical buttons to change the profile,
dpi or something else.

Still not hooked up in the library, but re-assigning back a different
hard-coded macro works.
This also re-introduce the dependency on libevdev for the lib.

the current driver API is not good enough. We should be able to say
which DPI setting we want to change. Thus, the external API is not
correct either.

We need to store the profile in each ratbag_resolution or we will not be
able to get back to the driver.
