The current tpa6130a2 driver supports only a single instance.
This patch series add support for multiple instances by removing the global

This is performed by using the component API, regmap, the

That's actually a fairly common thing to do. The reason is that
'current' is far more expensive to evaluate than a local variable.

Those slab caches are always allocated with the SLAB_RECLAIM_ACCOUNT,
meaning allocations from the caches are going to be accounted as
SReclaimable. At the same time btrfs is not registering any shrinkers

hif_drv->usr_scan_req.net.net_info[i] contains found_net_info structs

pstrNetworkInfo, of type network_info, also contains an u8 array named
