The bma180 IIO driver is being extended for support for the chips support by input's bma150 driver (bma023, bma150, smb380). Don't allow both drivers to be enabled simultaneously as they're for the same hardware. Signed-off-by:

Some variants of the bma180 (eg bma023) have different reset values. In preparation for adding support for them, factor out the reset value into the chip specific data. Reviewed-by:

When a station is removed, the driver check that all the Tx frames were correctly sent. However, the station can be removed before all the Tx frames were acknowledged and a false positive warning can be emitted. The previous commit has added a trace when driver received an acknowledge for a non-existent station. It appear that these events are perfectly correlated and there is no leak. Now, the subject is perfectly understood. Remove the warning. Just keep a debug trace in case we have any doubt in the future. In the past, the subject has already been discussed here: https://lore.kernel.org/driverdev-devel/6287924.ghGFUMk3OD@pc-42/ Fixes: 4bbc6a3e ("staging: wfx: make warning about pending frame less scary") Signed-off-by:

Some resources are associated to the outgoing of the stations. To avoid any resource leaks. It is important to understand why an acknowledge is not associated to any station. Add a trace for that purpose. Signed-off-by:

The function wfx_tx_flush() wait for there is no more queued frames in hardware queue. Then, for the sanity, it checks that there is no more pending frame on any AC queue. However, there is a race here. It may happens that hardware queues are empty, but the counters of the AC queues are not yet updated. So, it may produce false-positive warning. The easiest way to solve the problem is just to remove the sanity check. Signed-off-by:

When multiple vif are in use (= one access point and one station), and when the channels are different, it is necessary to enable power save on station. The firmware check that steps are done in the correct order: - AP can't start if PS is not enable on the station - PS can't set on the station before the association has finished (= before the call set_bss_params) Obviously, in add, when one of the interface disappears, it is necessary to restore the power save status. wfx_update_pm() is able to set the correct PS configuration. But it has to be called at the right time: 1. before hif_start(), but after the channel configuration is known 2. after hif_set_bss_params() 3. after hif_reset() Therefore, the call to wfx_update_pm() from wfx_add_interface() is too early to address 1. The call after hif_set_bss_params() already exists. For the symmetry, the call from wfx_remove_interface() (that handle 3.) is also relocated. Signed-off-by: -

The device disallows to start a scan request between hif_join() and hif_set_bss_params(). The driver is not protected against that. The worst case happens when association is aborted and hif_set_bss_params() never happens. mac80211 would never ask for scan during the association process. So, this patch just aborts the association in progress when scan is requested. Signed-off-by:

The function wfx_notify_buffered_tx() need to know if the frame was associated to a station. This information is available in the Control Buffer (CB) of the skb. However, when wfx_notify_buffered_tx() is called, the CB is no more available. Thus, the caller has to take care of this information. wfx_notify_buffered_tx() is a specific case. All the other function are called before the destruction of the CB. So, this patch align the API of wfx_notify_buffered_tx() with the other functions. Call it before the CB was destroyed and drop the extra argument 'has_sta'. It is also the right time to rename it into wfx_tx_update_sta() (which is closer to the behavior of the function).

The device does not answer to the command hif_shutdown. Therefore, hif_shutdown() is a bit special. It bypasses some of work normally made by wfx_cmd_send(). In particularly, it unlock hif_cmd.lock and hif_cmd.key_renew_lock. However, if the driver notice that the device is frozen, wfx_cmd_send() stops to send data and doesn't lock the mutexes. Then, it produced a warning when hif_shutdown() tried to unlock these mutexes. Signed-off-by:

This patch is removing definition of CFLAGS in Makefile of vt6656 and vt6655, as those are defining macros that are not used. This will remove undef of one macro from vt6655/device_main.c, as it is only undef and it is not used anywhere else, so it is safe to remove it. Macros are removed from vt665x/Makefile and vt6655/device_main.c. Signed-off-by:

Drop the driver version of the line-coding request and use the protocol definition directly as was originally intended instead. This specifically avoids having the two versions of what is supposed to be the same struct ever getting out of sync. Note that this has in fact already happened once when the protocol definition had its implicit padding removed while the driver struct wasn't updated. The fact that we used the size of the then larger driver struct when memcpying its content to the stack didn't exactly make things better. A later addition of a flow-control field incidentally made the structures match again. Signed-off-by:

In the start of the "vnt_rf_set_txpower" function the "power" variable is set at most to VNT_RF_MAX_POWER (hex = 0x3f, dec = 63). Then, in the switch statement there are four comparisons with the "power" variable against AL7230_PWR_IDX_LEN (dec = 64), VT3226_PWR_IDX_LEN (dec = 64), VT3342_PWR_IDX_LEN (dec = 64). Due to all the commented comparisons are to check if the "power" variable is "greater than or equal" to 64, this never happens. So, remove the logically dead code. Also, remove all the defines that are no longer required. Addresses-Coverity-ID: 1230228 ("Logically dead code") Fixes: f53d9f12 ("staging: vt6656: rf.c additional power.")
