I guess so, or else it won`t compile, because, *pvalue* is int*, *value* is
unsigned long*, and qemu_strtoul() require a unsigned long* for the last 
param.
And I guess that is why author use a local 'value'. I just want to make 
the patch
small for the reviewer, so I reuse most of original code.

but yes, maybe it can be:
rc = qemu_strtoul(buf, &endptr, base, (unsigned long *)pvalue);
