Provides a firmware-attributes class which enables the use of tunable knobs for SPL, SPPT, and FPPT. v3: - Add notifier block and store result for getting the Gamezone interface profile changes. - Add driver as master component of capdata01 driver. - Use FIELD_PREP where appropriate. - Move macros and associated functions out of lemovo-wmi.h that are only used by this driver. v2: - Use devm_kmalloc to ensure driver can be instanced, remove global reference. - Ensure reverse Christmas tree for all variable declarations. - Remove extra whitespace. - Use guard(mutex) in all mutex instances, global mutex. - Use pr_fmt instead of adding the driver name to each pr_err. - Remove noisy pr_info usage. - Rename other_method_wmi to lenovo_wmi_om_priv and om_wmi to priv. - Use list to get the lenovo_wmi_om_priv instance in some macro called functions as the data provided by the macros that use it doesn't pass a member of the struct for use in container_of. - Do not rely on GameZone interface to grab the current fan mode.
