[PATCH 00/14] simple cleanups in spapr files

[Daniel Henrique Barboza]

Hi,

These are some cleanups in spapr files I decided to make after seeing
Greg adding g_auto* in virtio-9p files.

I also took the opportunity to simplify the logic in some places where I
found it to be more complex than needed.

Aside from patch 02, no functional change was made in this series.

[PATCH 02/14] hw/ppc/spapr.c: fail early if no firmware found in machine_init()

[Daniel Henrique Barboza]

The firmware check consists on a file search (qemu_find_file) and load
it via load_imag_targphys(). This validation is not dependent on any
other machine state but it currently being done at the end of
spapr_machine_init(). This means that we can do a lot of stuff and end
up failing at the end for something that we can verify right out of the
gate.

Move this validation to the start of spapr_machine_init() to fail
earlier.  While we're at it, use g_autofree in the 'filename' pointer.

Keeping it close to where it's used, i.e. right here at the end of the 
declarations would be easier to read, considering that it also inits it 
right away so checking the value in the next line is more straight 
forward.

Grouping with the simliar filename variables is also reasonable but unless 
the value of those change later just removing them and using the 
machine->{kernel,initrd}_filename directly may be simpler. I did that 
before to mac machines to simplify code.

By the way those are declared const char *, does this filename needs to be 
const too? Maybe moving the bios_* vars here too makes more sense to keep 
them together.

[PATCH 06/14] hw/ppc/spapr_drc.c: use g_auto in spapr_dt_drc()

[Daniel Henrique Barboza]

Use g_autoptr() with GArray* and GString* pointers to avoid calling
g_free() and the need for the 'out' label.

'drc_name' can also be g_autofreed to avoid a g_free() call at the end
of the while() loop.

[PATCH 11/14] hw/ppc/spapr_numa.c: simplify spapr_numa_write_assoc_lookup_arrays()

[Daniel Henrique Barboza]

We can get the job done in spapr_numa_write_assoc_lookup_arrays() a bit
cleaner:

- 'cur_index = int_buf = g_malloc0(..)' is doing a g_malloc0() in the
'int_buf' pointer and making 'cur_index' point to 'int_buf' all in a
single line. No problem with that, but splitting into 2 lines is clearer
to follow

- use g_autofree in 'int_buf' to avoid a g_free() call later on

- 'buf_len' is only being used to store the size of 'int_buf' malloc.
Remove the var and just use the value in g_malloc0() directly

- remove the 'ret' var and just return the result of fdt_setprop()
