Subject: [PATCH] ipmi: replace call to try_smi_init() with call to add_smi()
Date: Tue, 08 Jan 2013 15:12:31 -0500 [thread overview]
Message-ID: <50EC7DAF.8030606@redhat.com> (raw)
In-Reply-To: <50CB3662.5080100@redhat.com>
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 ...
