[PATCH v3 5/6] platform-x86: lenovo-wmi-other: Rename LWMI_OM_FW_ATTR_BASE_PATH

[PATCH v3 5/6] platform-x86: lenovo-wmi-other: Rename LWMI_OM_FW_ATTR_BASE_PATH
Posted by Derek J. Clark 1 month, 1 week ago 
In the next patch a power supply extension is added which requires
a name attribute. Instead of creating another const macro with the
same information, replace LWMI_OM_FW_ATTR_BASE_PATH with
LWMI_OM_NAME and use that for firmware attributes and power supply
extension.

I placed it here intentionally as it has nothing to do with
LWMI_ATTR_ID (contrary to other fan-related macros) and is just a
descriptive macro.

Understandable. I think it makes sense to keep the fan related defines all together since I'll be adding additional LWMI_ATTR_ID defines here later.

This doesn't match the code change??

Woops, sorry, I forgot to update the variable name in the commit message after I changed it.

Thanks.
