The DEVICE() macro is defined as:
#define DEVICE(obj) OBJECT_CHECK(DeviceState, (obj), TYPE_DEVICE)
which expands to:
((DeviceState *)object_dynamic_cast_assert((Object *)(obj), (name),
__FILE__, __LINE__,
__func__))
This assertion can only fail when @obj points to something other
than its stated type, i.e. when we're in undefined behavior country.
Remove the unnecessary DEVICE() casts when we already know the
pointer is of DeviceState type.
Patch created mechanically using spatch with this script:
@@
typedef DeviceState;
DeviceState *s;
@@
- DEVICE(s)
+ s

In my "build everything" tree, changing migration/vmstate.h triggers a
recompile of some 2700 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).
hw/hw.h supposedly includes it for convenience. Several other headers
include it just to get VMStateDescription. The previous commit made
that unnecessary.
Include migration/vmstate.h only where it's still needed. Touching it
now recompiles only some 1600 objects.

In my "build everything" tree, changing hw/irq.h triggers a recompile
of some 5400 out of 6600 objects (not counting tests and objects that
don't depend on qemu/osdep.h).
hw/hw.h supposedly includes it for convenience. Several other headers
include it just to get qemu_irq and.or qemu_irq_handler.
Move the qemu_irq and qemu_irq_handler typedefs from hw/irq.h to
qemu/typedefs.h, and then include hw/irq.h only where it's still
needed. Touching it now recompiles only some 500 objects.

i2c_recv() cannot fail, so there is no need to check the return
value. It also returns unt8_t, so comparing with < 0 is not
meaningful.
Fix up various I2C controllers to remove the unneeded code.

The imx25 chip provides 3 i2c buses, but they have all been named
"i2c", which makes it difficult to predict which bus a device will
be connected to when specified on the command line.
This patch addresses the issue by naming the buses uniquely:
i2c-bus.0 i2c-bus.1 i2c-bus.2

The goal is to have debug code always compiled during build.
We standardize all debug output on the following format:
[QOM_TYPE_NAME]reporting_function: debug message
The qemu_log_mask() output is following the same format as
the above debug.
