ra_list_spinlock is used to protect struct mwifiex_wmm_desc and embedded structures such as ra_list. tid_tbl_lock while more fine grained, is not used but in one function. That function is not called reentrantly. To protect ra_list from concurrent modification ra_list_spinlock must be held. Signed-off-by:

adapter->bss_prio_tbl list has already been checked in outer loop. The inner loop works with priv_tmp->wmm.tid_tbl_ptr list. Also the lock taken, gives hint that this is likely a copy-paste error. Signed-off-by:

These are the remaining knobs in ath9k to support DFS: * mark AR9280 and AR9580 as DFS tested * synchronize DFS regulatory domain to reg notifyer * set required RX filter flags for radar detection * process radar PHY errors at DFS detector * notify DFS master on radar detection DFS support requires CONFIG_ATH9K_DFS_CERTIFIED to be set.

cmd_pending is increased in mwifiex_wait_queue_complete() and decreased in mwifiex_complete_cmd() currently. If there are two or more commands in the cmd_pending_q the main worker thread will pick up next command from cmd_pending_q automatically after finishing current command. As a result mwifiex_wait_queue_complete() will not be called because the command is alreay completed. This leads to a negative number in cmd_pending count. Fix it by increasing cmd_pending when a cmd is queued into cmd_pending_q and decreasing when that cmd is recycled. For scan commands we don't perform inc/dec operations until it's moved from scan_pending_q to cmd_pending_q. This covers both synchronous and asynchronous commands. Reported-by:

Firmware provides the driver with credits used to transmit packets to the firmware. When credits run out the packets should be queued and dequeued when receiving creditback signals from the firmware. Reviewed-by:

If iovar to the firmware fails the firmware-signalling module does a cleanup for which it needs pointer to struct brcmf_pub, which it gets from struct brcmf_fws_info::drvr. Assign this field before doing the tlv iovar. Reviewed-by:

The low-level sdio code has a large number of trace and info messages that are mostly useful looking into bus specific issues. For tracing higher-level driver functions it is better to have a dedicated level for low-level sdio debugging. Reviewed-by:

Parsing the tlv upon receiving frames can fail. Instead of printing an error message, just count the parse failure. On some devices we receive a lot of invalid tlv signals. this commit will be squashed. Signed-off-by:

When firmware-signalling is active the brcmf_txcomplete() does a free of the sk_buff when transfer to firmware fails in the bus-specific driver code. However, it should also cleanup the packet from the hanger. This patch fixes that. Reviewed-by:

In brcmf_sdbrcm_txpkt() a new packet is allocated and used to transmit to firmware freeing up the original packet. However, that packet is still referenced in firmware-signalling so this would result in a double free. Using skb_cow() avoids this as the packet reference is unchanged. Reviewed-by:

When taking care of packet alignment to 64-byte boundary padding may be added between SDPCM header and CDC data. It clear both SDPCM header space and padding space. Changed it to only clear padding space. In filling the SDPCM header it uses unaligned access to set SDPCM software header, but preceding code assures it is properly aligned. Signed-off-by:
