[Qemu-trivial] [PATCH v2 0/4] Small optimizations for code using g_malloc0 + memset/memcpy

[Thomas Huth]

There are a couple of spots in the QEMU code which use g_malloc0,
directly followed by a memset or memcpy which fill the whole
allocated buffer. In this case it either does not make sense to
zero the buffer via g_malloc0 first (so g_malloc should be used
instead), or if the second command is a memset(..., 0, ...), then
the memset does not make much sense, of course, since the buffer
has already been zeroed by the g_malloc0.

v2:
- Switched some of the g_malloc0()s to g_new0()s where appropriate
- Added Reviewed-by-s
- The spapr_vscsi patch has been picked up by David already, so not
  sending it again

Thomas Huth (4):
  hw/dma/pxa2xx: Remove superfluous memset
  hw/input/tsc210x: Remove superfluous memset
  tests/i44fx-test: No need for zeroing memory before memset
  linux-user/syscall: Replace g_malloc0 + memcpy with g_memdup
