/usr/include/alsa/pcm.h contains:
#define snd_pcm_sw_params_alloca(ptr) do { assert(ptr); *ptr = (snd_pcm_sw_params_t *) alloca(snd_pcm_sw_params_sizeof()); memset(*ptr, 0, snd_pcm_sw_params_sizeof()); } while (0)
The assert generates: "error: the address of 'sw_params' will always
evaluate as 'true'" which combined with -Werror prevents alsaaudio.o
from being built with certain versions of GCC.
The sequence of reading from eeprom is "offset by one" moved because of a false
detection of a clock cycle after an eeprom reset. Keeping the last clock value
after a reset keeps it in sync.

Add id field to DeviceState. Make "info qtree" print it.
This helps users and management apps identifying devices in monitor
output, which is especially useful with otherwise identical devices
such as two virtio disks.
This patch doesn't add a way to set the id, followup patches will do.

no_user: prevent users from adding certain devices.
desc: description of the device.
alias: to allow user friendly shortcuts on the command line, i.e.
-device usbmouse instead of -device "QEMU USB Mouse" or
-device lsi instead of -device lsi53c895a

This add support for switching devices into a compatibility mode
using device properties. Machine types can have a list of properties
for specific devices attached to allow the easy creation of machine
types compatible to older qemu versions.

This patch is a major overhaul of the device properties. The properties
are saved directly in the device state struct now, the linked list of
property values is gone.
Advantages:
* We don't have to maintain the list with the property values.
* The value in the property list and the value actually used by
the device can't go out of sync any more (used to happen for
the pci.devfn == -1 case) because there is only one place where
the value is stored.
* A record describing the property is required now, you can't set
random properties any more.
There are bus-specific and device-specific properties. The former
should be used for properties common to all bus drivers. Typical
use case is bus addressing, i.e. pci.devfn and i2c.address.
Properties have a PropertyInfo struct attached with name, size and
function pointers to parse and print properties. A few common property
types have PropertyInfos defined in qdev-properties.c. Drivers are free
to implement their own very special property parsers if needed.
Properties can have default values. If unset they are zero-filled.
