[Linux-stable-mirror] Request backport of "ipmi: Prefer ACPI system interfaces over SMBIOS ones"

by Corey Minyard

I'm requesting a backport of 7e030d6dff713250c7dcfb543cad2addaf479b0e ipmi: Prefer ACPI system interfaces over SMBIOS ones to the 4.14 stable kernel tree only. This was already staged for Linus in my public tree before Andrew noticed an issue that this patch fixes, where the system can oops when the ipmi_si module is removed. Since it fixes an oops that likely can affect people, I'd like it to be added to the stable tree, Since this bug was added in 4.13 by: 0944d889a237b6107f9ceeee053fe7221cdd1089 ipmi: Convert DMI handling over to a platform device it should only require a backport to 4.14. Thank you, -corey
