The rule of not using braces in single statement does not apply if only one branch of the conditional statement is a single statement. Add braces to fix this. While at it, remove extra blank space after a comment inside the if block. Reported by checkpatch.pl Signed-off-by:

Since commit 5561770f ("staging: wfx: repair external IRQ for SDIO"), wfx_sdio_irq_subscribe() enforce the device to use IRQs. However, there is currently a race in this code. An IRQ may happen before the IRQ has been registered. The problem has observed during debug session when the device crashes before the IRQ set up: [ 1.546] wfx-sdio mmc0:0001:1: started firmware 3.12.2 "WF200_ASIC_WFM_(Jenkins)_FW3.12.2" (API: 3.7, keyset: C0, caps: 0x00000002) [ 2.559] wfx-sdio mmc0:0001:1: time out while polling control register [ 3.565] wfx-sdio mmc0:0001:1: chip is abnormally long to answer [ 6.563] wfx-sdio mmc0:0001:1: chip did not answer [ 6.568] wfx-sdio mmc0:0001:1: hardware request CONFIGURATION (0x09) on vif 2 returned error -110 [ 6.577] wfx-sdio mmc0:0001:1: PDS bytes 0 to 12: chip didn't reply (corrupted file?)

The 'channel' argument of hif_join() should never be NULL. hif_join() does not have the responsibility to recover bug of caller. In current code, if the argument channel is NULL, memory leaks. The new code just emit a warning and does not give the illusion that it is supported (and indeed a Oops will probably raise a few lines below). Signed-off-by:

The PDS file contains antenna parameters. The file is specific to each hardware design. Normally, the board designer should add a line in the of_device_id table with his own antenna parameters. Until, now the absence of PDS file is a hard fatal error. However, during the development, in most of the cases, an empty PDS file is sufficient to start WiFi communication. This patch keep an error, but allow the user to play with the device. Signed-off-by:

The WF200 is able to filter beacons. However, it uses a positive filter: any change to an IE not listed won't be reported. In current code, the changes in Channel Switch Announcement (CSA) are not reported to the host. Thus, it fixes the support for CSA in station mode. Signed-off-by:

It is no more necessary to compute the expected duration of the scan request. Signed-off-by:
-
Jérôme Pouiller authored
If the environment is noisy, the device may take time to send scan requests. Thus, scan requests durations > 5s have already been observed. During the scan, traffic is neither received, neither sent. From the user point-of-view, the traffic is frozen for a long time. This patch reworks the scan processing. It gives to the device a smaller time budget than previously. However, it does not expect the scan to be complete and it is able to send another scan request to finish the work. A big part of the patch aims to avoid an infinite loop if the device goes crazy. Signed-off-by:
-
Jérôme Pouiller authored
When the device has finished a scan request, it send a scan complete ("SCAN_COMPL") indication. It is also possible to abort a scan request with a "SCAN_STOP" message. A SCAN_COMPL is also send in this case. The driver limits the delay to make a scan request. A timeout happens almost never but is theoretically possible. Currently, if it happens the driver does not wait for the SCAN_COMPL. Then, when the driver starts the next scan request, the device may return -EBUSY (scan requests often occur back-to-back). This patch give a chance to the device to send a SCAN_COMPL after a scan timeout. Signed-off-by: -

When multiple interface are in use. One is always AP while the other is always station. When the two interface use the same channel, it makes no sense to enabled Power Saving (PS) on the station. Indeed, because of the AP, the device will be kept awake on this channel anyway. In add, when multiple interface are in use, mac80211 does not update the PS information and delegate to the driver responsibility to do the right thing. Thus, in the current code, when the user enable PS in this configuration, the driver finally enable PS-Poll which is probably not what the user expected. This patch detect this case and applies a sane configuration in all cases. Signed-off-by:

Jérôme Pouiller authored
During the scan requests, the Tx traffic is suspended. This lock is shared by all the network interfaces. So, a scan request on one interface will block the traffic on a second interface. This causes trouble when the queued traffic contains CAB (Content After DTIM Beacon) since this traffic cannot be delayed. It could be possible to make the lock local to each interface. But It would only push the problem further. The device won't be able to send the CAB before the end of the scan. So, this patch just ignore the DTIM indication when a scan is in progress. The firmware will send another indication on the next DTIM and this time the system will be able to send the traffic just behind the beacon. The only drawback of this solution is that the stations connected to the AP will wait for traffic after the DTIM for nothing. But since the case is really rare it is not a big deal. Signed-off-by:

Jérôme Pouiller authored
The wfx driver checks carefully the coherency of of the DTIM notifications. We have noticed several times some small inconsistencies from the firmware on these notification. They have never been critical. However on the driver side they lead to big fat warnings. Worse, if these warning are displayed on UART console, they can be long to display (several hundreds of millisecs). Since, this warning is generated from a work queue, it can delay all the workqueue users. Especially, it can drastically slow down the frame management of the driver and then generate errors that are serious this time (eg. an overflow of the indication queue of the device). Signed-off-by:
