This patchset is a collection of fixes for minor Coverity reported
issues. In all cases, there isn't a user-visible problem, but
the Coverity issue pointed up somewhere where we could clean
up the code or make it a bit more obvious to a human reader
what the intent was.

Only lightly tested (with "make check" and "make check-avocado").

thanks

Peter Maydell (7):
  block/vdi.c: Avoid potential overflow when calculating size of write
  block/gluster: Use g_autofree for string in qemu_gluster_parse_json()
  hw/block/pflash_cfi01: Don't decrement pfl->counter below 0
  hw/ide/atapi: Be explicit that assigning to s->lcyl truncates
  hw/block/fdc-isa: Assert that isa_fdc_get_drive_max_chs() found
    something
  hw/ide/pci.c: Remove dead code from bmdma_prepare_buf()
  block/ssh.c: Don't double-check that characters are hex digits
