If the WLAN core is still active during initialization, it might cause
the MCU or DMA to hang. This can happen during soft reboot, so disable
the core + clock early to avoid this issue.

mt76 uses __skb_pad() with free_on_error set to true, this is the same
as calling skb_pad().
This patch does not change any functionality, but it makes it easier to
backport this driver in backports, because skb_pad() is also available
in older kernel versions.

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 = kmalloc(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 = kmalloc(struct_size(instance, entry, count), GFP_KERNEL);
This patch makes the changes for kmalloc()-family (and kvmalloc()-family)
uses. It was done via automatic conversion with manual review for the
"CHECKME" non-standard cases noted below, using the following Coccinelle
script:
// pkey_cache = kmalloc(sizeof *pkey_cache + tprops->pkey_tbl_len *
// sizeof *pkey_cache->table, GFP_KERNEL);

identifier alloc =~ "kmalloc|kzalloc|kvmalloc|kvzalloc";

Using the NAPI or netdev frag cache along with other drivers can lead to
32 KiB pages being held for a long time, despite only being used for
very few page fragments.
This can happen if the driver grabs one or two fragments for rx ring
refill, while other drivers use (and free up) the remaining fragments.
The 32 KiB higher-order page can only be freed once all users have freed
their fragments.
Depending on the traffic patterns, this can waste a lot of memory and
look a lot like a memory leak.
