cpufreq: Make cpufreq_driver->exit() return void

2024-07-09T03:15:30+00:00

The cpufreq core doesn't check the return type of the exit() callback
and there is not much the core can do on failures at that point. Just
drop the returned value and make it return void.

cpufreq: e_powersaver: remove unreachable break

2020-10-27T17:42:54+00:00

A 'break' following a 'return' statement is pointless, so remove it.

cpufreq: Convert to new X86 CPU match macros

2020-03-24T20:31:27+00:00

The new macro set has a consistent namespace and uses C99 initializers
instead of the grufty C89 ones.

Get rid the of most local macro wrappers for consistency. The ones which
make sense for readability are renamed to X86_MATCH*.

In the centrino driver this also removes the two extra duplicates of family
6 model 13 which have no value at all.

cpufreq: e_powersaver: Use struct_size() in kzalloc()

2019-01-15T21:58:59+00:00

One of the more common cases of allocation size calculations is
finding the size of a structure that has a zero-sized array at
the end, along with memory for some number of elements for that
array. For example:

struct foo {
    int stuff;
    void *entry[];
};

instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we
can now use the new struct_size() helper:

instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);

This code was detected with the help of Coccinelle.

cpufreq: e_powersaver: Don't validate the frequency table twice

2018-03-20T11:07:52+00:00

The cpufreq core is already validating the CPU frequency table after
calling the ->init() callback of the cpufreq drivers and the drivers
don't need to do the same anymore. Though they need to set the
policy->freq_table field directly from the ->init() callback now.

Stop validating the frequency table from e_powersaver driver.

cpufreq: e_powersaver: Use IS_ENABLED() instead of checking for built-in or module

2016-04-27T20:42:34+00:00

The IS_ENABLED() macro checks if a Kconfig symbol has been enabled either
built-in or as a module, use that macro instead of open coding the same.

acpi_processor_unregister_performance() actually doesn't use its
first argument, so drop it and update the callers accordingly.
