Subject: ipmi_si: fix memory leak on new_smi
From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
[ Upstream commit c0a32fe13cd323ca9420500b16fd69589c9ba91e ]
The error exit path omits kfree'ing the allocated new_smi, causing a memory
leak. Fix this by kfree'ing new_smi.
Detected by CoverityScan, CID#14582571 ("Resource Leak")
Fixes: 7e030d6dff71 ("ipmi: Prefer ACPI system interfaces over SMBIOS ones")
