Currently, links in an interface are allocated during channel assignment
via assign_vif_chanctx(). Conversely, links are deleted during channel
unassignment via unassign_vif_chanctx(). However, deleting links during
channel unassignment does not comply with mac80211 link handling.
Therefore, this process should be managed within change_vif_links().
This series aims to add support to handle links in change_vif_links()
callback.
Patches 1-2 are making debug infra to work without device info.
Patches 3-8 are the ones changing the code to handle as mentioned above.
NOTE:
* A new ath12k-check warning comes which probably needs to be added to
ignore list
drivers/net/wireless/ath/ath12k/debug.c:69: Prefer [subsystem eg: netdev]_dbg([subsystem]dev, ... then dev_dbg(dev, ... then pr_debug(... to printk(KERN_DEBUG ...
This is because, since device info is not known can not use netdev_ or dev_
dbg family. pr_debug() is an option but that will require DYNAMIC_DEBUG
and then ath12k needs to be probed with dyndbg=+p which we don't want in
ath. Hence, only option left is to use printk() directly.
