SDIO may need addtional 511 bytes to align bus operation. If the tailroom of this skb is not big enough, we would access invalid memory region. For low level operation, increase skb size to keep valid memory access in SDIO host.

The driver uses ieee80211_iterate_active_interfaces_atomic() and ieee80211_iterate_stations_atomic() in several places and does register accesses in the iterators. This doesn't cope with upcoming USB support as registers can only be accessed non-atomically. Split these into a two stage process: First use the atomic iterator functions to collect all active interfaces or stations on a list, then iterate over the list non-atomically and call the iterator on each entry.

coex->mutex is used in rtw_coex_info_request() only. Most callers of this function hold rtwdev->mutex already, except for one callsite in the debugfs code. The debugfs code alone doesn't justify the extra lock, so acquire rtwdev->mutex there as well and drop the now unnecessary spinlock. Signed-off-by:

The rtwdev->rf_lock spinlock protects the rf register accesses in rtw_read_rf() and rtw_write_rf(). Most callers of these functions hold rtwdev->mutex already with the exception of the callsites in the debugfs code. The debugfs code doesn't justify an extra lock, so acquire the mutex there as well before calling rf register accessors and drop the now unnecessary spinlock. Signed-off-by:
