[Qemu-devel] [PULL 32/48] ipmi: introduce an ipmi_bmc_sdr_find() API

[David Gibson <david@gibson.dropbear.id.au>]

From: Cédric Le Goater <clg@kaod.org>

This patch exposes a new IPMI routine to query a sdr entry from the
sdr table maintained by the IPMI BMC simulator. The API is very
similar to the internal sdr_find_entry() routine and should be used
the same way to query one or all sdrs.

A typical use would be to loop on the sdrs to build nodes of a device
tree.
