      ipmi: bt-bmc: Use a regmap for register access · eb994594
      Andrew Jeffery authored 
      The registers for the bt-bmc device live under the Aspeed LPC
controller. Devicetree bindings have recently been introduced for the
LPC controller where the "host" portion of the LPC register space is
described as a syscon device. Future devicetrees describing the bt-bmc
device should nest its node under the appropriate "simple-mfd", "syscon"
compatible node.

This change allows the bt-bmc driver to function with both syscon and
non-syscon- based devicetree descriptions by always using a regmap for
register access, either retrieved from the parent syscon device or
instantiated if none exists.

      char: ipmi: constify ipmi_smi_handlers structures · db3b7e13
      Bhumika Goyal authored 
      Declare ipmi_smi_handlers structures as const as they are only passed as
an argument to the function ipmi_register_smi. This argument is of type
const, so ipmi_smi_handlers structures having similar properties can be
declared const too.
Done using Coccinelle:

@r1 disable optional_qualifier@
identifier i;
position p;
@@
static struct ipmi_smi_handlers i@p={...};
