[PATCH] drivers base/arch_topology: Remove 'struct sched_domain' forward declaration

[Dietmar Eggemann]

The sched domain pointer argument from topology_get_freq_scale() and
topology_get_cpu_scale() got removed by commit 7673c8a4c75d
("sched/cpufreq: Remove arch_scale_freq_capacity()'s 'sd' parameter")
and commit 8ec59c0f5f49 ("sched/topology: Remove unused 'sd' parameter
from arch_scale_cpu_capacity()").

So the 'struct sched_domain' forward declaration is no longer needed.
Remove it.

W/o the sched domain pointer argument the storage class and inline
definition as well as the return type, function name and parameter list
fit all into one line.

You are doing two different things in this patch :(

Reformatting the function names are fine, but that has nothing to do
with dropping the "struct sched_domain;" line.  Please split into 2
different patches.

thanks,

Will do. I'll keep the patch like it is. Thanks for the review!

Looks simple and good to me. I don't want to ask you split the patch as
$subject indicates only one of the 2 changes in the patch. I am fine with
it as it but if anyone else shout for that, go for the split.

Either way,

You have not added Greg who generally picks up the patch. Can you repost
with him in cc and my reviewed-by so that he can pick it up.

[PATCH] drivers base/arch_topology: Remove 'struct sched_domain' forward declaration

The sched domain pointer argument from topology_get_freq_scale() and
topology_get_cpu_scale() got removed by commit 7673c8a4c75d
("sched/cpufreq: Remove arch_scale_freq_capacity()'s 'sd' parameter")
and commit 8ec59c0f5f49 ("sched/topology: Remove unused 'sd' parameter
from arch_scale_cpu_capacity()").

So the 'struct sched_domain' forward declaration is no longer needed.
Remove it.

W/o the sched domain pointer argument the storage class and inline
definition as well as the return type, function name and parameter list
fit all into one line.
