Subject: [PATCH] ipmi: replace call to try_smi_init() with call to add_smi()

Upstream commit 9e368fa0 added function ipmi_pnp_probe(), which
calls try_smi_init() directly.

try_smi_init() allocates resources for IPMI driver. However
try_smi_init() can be called again, and the allocated resources
can be unexpectedly released when the same IPMI resource
information is found on both ACPI namespace and SMBIOS table.
ipmi_pnp_probe() should call add_smi() instead of try_smi_init()

For reference, see upstream commit ...
