[PATCH 0/7] trivial: Replace some qemu_open_old() with qemu_open()

[PATCH 0/7] trivial: Replace some qemu_open_old() with qemu_open()

[Zhao Liu]

Hi list,

After Daniel's renaming (448058aa99aa "util: rename qemu_open() to
qemu_open_old()"), I find some qemu_open_old() can be directly replaced
by the new qemu_open().

This series considers the case where @errp exists, for which @errp can
be passed directly to qemu_open().

There would be more cleanup to help qemu_open_old() retire as early as
possible.

Thanks and Best Regards,
Zhao

So replace qemu_open_old() with qemu_open(). And considering the SGX
enablement description is useful, convert it into a error message hint.

So replace qemu_open_old() with qemu_open(). And considering
rng_random_opened() will lose its obvious error handling case after
removing error_setg_file_open(), add comment to remind here.
