[PATCH v1 0/5] ACPI: thermal: Assorted cleanups

[PATCH v1 0/5] ACPI: thermal: Assorted cleanups

[Rafael J. Wysocki]

Hi Folks,

These patches clean up the ACPI thermal driver in a few different ways and
none of them is expected to affect the functionality.

Thanks!

[PATCH v1 1/5] ACPI: thermal: Use BIT() macro for defining flags

[Rafael J. Wysocki]

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Use the BIT() macro for defining flag symbols in the ACPI thermal driver
instead of using "raw" values for the flags.

No functional impact.

[PATCH v1 2/5] ACPI: thermal: Drop redundant ACPI_TRIPS_REFRESH_DEVICES symbol

[Rafael J. Wysocki]

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Drop the ACPI_TRIPS_REFRESH_DEVICES symbol which is redundant, because
ACPI_TRIPS_DEVICES can be used directly instead of it without any
drawbacks and rename the ACPI_TRIPS_REFRESH_THRESHOLDS to
ACPI_TRIPS_THRESHOLDS to make the code a bit more consistent.

While at it, fix up some formatting white space used in the symbol
definitions.

No functional impact.

[PATCH v1 3/5] ACPI: thermal: Move symbol definitions to one place

[Rafael J. Wysocki]

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Move all of the symbol definitions to the initial part of the code so
they all can be found in one place.

While at it, consolidate white space used in there.

No functional impact.

[PATCH v1 4/5] ACPI: thermal: Move acpi_thermal_driver definition

[Rafael J. Wysocki]

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Move the definition of the acpi_thermal_driver structure closer to the
initialization code that registes the driver, so some function forward
declarations can be dropped.

Also move the module information to the end of the file where it is
usually located.

No functional impact.

[PATCH v1 5/5] ACPI: thermal: Eliminate struct acpi_thermal_state_flags

[Rafael J. Wysocki]

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Notice that the enabled flag is only needed for active trip points,
so drop struct acpi_thermal_state_flags, add a simple "bool valid" field
to the definitions of all trip point structures instead of flags and
add a "bool enabled" field to struct acpi_thermal_active.

Adjust the code using the modified structures accordingly.

No intentional functional impact.
