g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This series only touches allocations with size arguments of the form
sizeof(T). It's mechanical, except for a tiny fix in PATCH 2.
PATCH 1 adds the Coccinelle script.
PATCH 2 cleans up the virtio-9p subsystem, and fixes a harmless typing
error uncovered by the cleanup.
PATCH 3 cleans up everything else. I started to split it up, but
splitting is a lot of decisions, and I just can't see the value.
For instance, MAINTAINERS tells me to split for subsystem "virtio",
patching
hw/char/virtio-serial-bus.c
hw/display/virtio-gpu.c
hw/net/virtio-net.c
hw/virtio/virtio-crypto.c
hw/virtio/virtio-iommu.c
hw/virtio/virtio.c
But it also tells me to split for subsystem "Character devices",
patching
hw/char/parallel.c | 2 +-
hw/char/riscv_htif.c | 2 +-
hw/char/virtio-serial-bus.c | 6 +-
and for subsystem "Network devices", patching
hw/net/virtio-net.c
and for subsystem "virtio-gpu", patching
hw/display/virtio-gpu.c
I guess I'd go with "virtio". Six files down, 103 to go. Thanks, but
no thanks.
Since the transformation is local to a function call, dropping is
completely safe. We can deal with conflicts by dropping conflicting
hunks, with "git-pull -s recursive -X ours". Or drop entire files
with conflicts.
If you want me to split off certain parts, please tell me exactly what
you want split off, and I'll gladly do the splitting. I don't mind
the splitting part, I do mind the *thinking* part.
I backed out two changes made by the Coccinelle script:
scripts/coverity-scan/model.c, because that's special, and
semihosting/config.c, because it has a typing error similar to the one
fixed in PATCH 2, and Alex already posted a patch for it.
v2:
* PATCH 3: Change to scripts/coverity-scan/model.c dropped [Eric]
* PATCH 3: Change to semihosting/config.c dropped [Alex]
* Commit messages tweaked

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form
sizeof(T).
Initial patch created mechanically with:
$ spatch --in-place --sp-file scripts/coccinelle/use-g_new-etc.cocci \
--macro-file scripts/cocci-macro-file.h FILES...
This uncovers a typing error:
../hw/9pfs/9p.c: In function ‘qid_path_fullmap’:
../hw/9pfs/9p.c:855:13: error: assignment to ‘QpfEntry *’ from incompatible pointer type ‘QppEntry *’ [-Werror=incompatible-pointer-types]
855 | val = g_new0(QppEntry, 1);
| ^
Harmless, because QppEntry is larger than QpfEntry. Manually fixed to
allocate a QpfEntry instead.

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form
sizeof(T).
Patch created mechanically with:
$ spatch --in-place --sp-file scripts/coccinelle/use-g_new-etc.cocci \
--macro-file scripts/cocci-macro-file.h FILES...
