Subject: [PATCH] ipmi_si: fix crash on parisc
Git-commit: 51614b26a029515dd3bc43a8c0e16a9ee51bbf52
Patch-mainline: v4.15-rc4
References: FATE#326156
This patch fixes ipmi crash on parisc introduced in the kernel 4.15-rc.
The pointer io.io_setup is not initialized and thus it causes crash in
try_smi_init when attempting to call new_smi->io.io_setup.
