[PATCH net-next] wifi: ath11k: Use list_count_nodes()

[PATCH net-next] wifi: ath11k: Use list_count_nodes()

[Christophe JAILLET]

ath11k_wmi_fw_stats_num_vdevs() and ath11k_wmi_fw_stats_num_bcn() really
look the same as list_count_nodes(), so use the latter instead of hand
writing it.

The first ones use list_for_each_entry() and the other list_for_each(), but
they both count the number of nodes in the list.

While at it, also remove to prototypes of non-existent functions.
Based on the names and prototypes, it is likely that they should be
equivalent to list_count_nodes().

I'll run sanity tests on ath11k patches. I'll also add "Compile tested
only" to the commit log.

Oh, and ath11k patches go to ath tree, not net-next.

Hi,

[adding Joe Perches]

maybe checkpatch could be instrumented for that?

Something that would print a warning if the MAINTAINERS file has a git 
repo in T: or if F: states something related to 'net'.


WARNING: Your patch is against the xxx.git repo but the subject of the 
mail does not reflect it. Should [PATCH xxx] be used instead?
Also make sure that it applies cleanly on xxx.git to ease merge process.

WARNING: Your patch is related to 'net'. Such patches should state 
[PATCH net] when related to bug fix, or [PATCH net-next] otherwise.

Eventually, something if net-next is closed?


What do you think?
Would it be possible? Would it help?

Just for awareness, there are 2 additional patches apparently targeting
net-next but being instead for the WiFi tree:

BTW I prefer to have "Compile tested only" in the commit log to make it
clear that it's not tested on a real device. So I added that sentence to
both this and ath10k patch.
