Warnings with GCC 9.3

[Pranith Kumar]

Hello,

I keep seeing these warnings on the latest master with GCC 9.3:

/home/pranith/qemu/hw/block/pflash_cfi01.c: In function
‘pflash_mem_read_with_attrs’:

/home/pranith/qemu/hw/block/pflash_cfi01.c:667:20: note: parameter passing
for argument of type ‘MemTxAttrs’ {aka ‘struct MemTxAttrs’} changed in GCC
9.1
  667 | static MemTxResult pflash_mem_read_with_attrs(void *opaque, hwaddr
addr, uint64_t *value,

      |                    ^~~~~~~~~~~~~~~~~~~~~~~~~~


Are there any patches in queue to fix this before the release?

Thanks,
