_______________________________________________________
Details:
There is a check in the code, but I think the condition must cover all the
following lines not just the first one:
Original:
if (o)
grub_dma_free (o->td_chunk);
grub_dma_free (o->ed_bulk_chunk);
grub_dma_free (o->ed_ctrl_chunk);
grub_dma_free (o->hcca_chunk);
grub_free (o);
My version:
if (o)
{
grub_dma_free (o->td_chunk);
grub_dma_free (o->ed_bulk_chunk);
grub_dma_free (o->ed_ctrl_chunk);
grub_dma_free (o->hcca_chunk);
grub_free (o);
}
Patch is submitted.
(Bug was found by cppcheck 1.47.)
