This series of patches makes various cleanups to the spitz board
family code; the main driver here was fixing the minor Coverity
nit CID 1421913, which is a complaint that the call to
qemu_allocate_irqs() creates memory that is leaked.
We fix this by replacing the free-standing irq array and
callback function with a proper QOM device TYPE_SPITZ_MISC_GPIO,
which can have its own GPIO inputs and outputs which we can wire
up as appropriate. This also allows us to remove the ugly
file-scope variables that pointed to some of the devices on the
board so that the old callback function could prod them.
For this to work we need to add QOM properties and input GPIOs
to the max111x ADC devices so that we can control them that
way rather than by direct calls to max111x_set_input().
While we're in that bit of old code we take the opportunity to
get rid of its call to vmstate_register() and to give it a reset
method and a header file so we can document it a bit better.
The last few patches are unrelated cleanup that I noticed in
passing: we reduce the use of the zaurus_printf() macro in favour
of LOG_GUEST_ERROR logging for bad register accesess, and we
get rid of the old FROM_SSI_SLAVE which can be replaced with
QOM cast macros.
Patch 1 removes the hardcoded tabs in spitz.c, because they've
escaped our usual "fix as we touch a file" policy long enough,
and it's easier to do a wholesale detabify of the file before
starting.
As you review this series you might notice some other things in the
code that could also be cleaned up; so did I, but I felt that
17 patches was quite enough to be going on with :-)
thanks
