Whilst this enables ACPI binding or the device via PRP0001 the primary aim is to remove potential for these two things to be cut and paste into new drivers. Signed-off-by:

Replace the for loops of the vnt_update_top_rates function by the fls function. The purpose of the two for loops is to find the most significant bit set in a range of bits. So, they can be replace by the fls function (find last set) with a previous mask to define the range. This way avoid the iteration over unnecessary for loops. The header "linux/bits.h" can be remove as it is included in the header "linux/bitops.h". Signed-off-by:

Replace the for loop by a ternary operator whose condition is an AND bitmask against the priv->basic_rates variable. The purpose of the for loop was to check if any of bits from RATE_54M to RATE_6M was set, but it's not necessary to check every individual bit. The same result can be achieved using only one single mask which comprises all the commented bits. This way avoid the iteration over an unnecessary for loop. Also change the return type to bool because it's the type that this function returns. Signed-off-by:

gasket_sysfs_register_store() invokes get_mapping(), which returns a reference of the specified gasket_sysfs_mapping object to "mapping" with increased refcnt. When gasket_sysfs_register_store() returns, local variable "mapping" becomes invalid, so the refcount should be decreased to keep refcount balanced. The reference counting issue happens in one exception handling path of gasket_sysfs_register_store(). When gasket_dev is NULL, the function forgets to decrease the refcnt increased by get_mapping(), causing a refcnt leak. Fix this issue by calling put_mapping() when gasket_dev is NULL. Signed-off-by:

In wfx_remove_interface(), the current code differentiate AP and Station cases. However, it is not necessary. In all cases, the only important thing is the call to hif_reset(). We can use the same code to support all cases. Signed-off-by:

The callers of wfx_do_unjoin() already take care of vif state. Therefore, it is not necessary to take care of the status of the interface. Signed-off-by:

In former code (before the inclusion of the driver in mainline kernel), hif_join() could run asynchronously. When a join request was in progress, it was forbidden to launch hif_scan(). Now, hif_join() is always run synchronously. There is no more reasons to keep a protection against this case. Signed-off-by:

Basic Rates are already set by hif_join(). hif_join() is also able to manage possible changes after association. Firmware also allows to change the Basic Rates with hif_set_association_mode() but it does not bring anything in our case. Signed-off-by:

The structure hif_req_set_bss_params come from hardware API. It is not intended to be manipulated in upper layers of the driver. In add, current code for hif_req_set_bss_params() is too dumb. It should pack data with hardware representation instead of leaving all work to the caller. Signed-off-by:

Dual CTS is only necessary when sending/receiving STBC data. However, the chip does not support STBC, so it is never necessary to enable double CTS. We can simplify the code. Signed-off-by:

Current code skip some configuration during joining an IBSS network. Indeed, it seems that this configuration is not used in IBSS. However, it would be harmless to set them. In add, we would prefer to keep association processes for ad-hoc and managed networks the closest as possible. It also ensures the values of internal parameters of the firmware. Therefore, apply them unconditionally. Signed-off-by:

Currently, events from firmware are handled in a work queue with a complex event queue mechanism. It is probably overkill since there is only two events to handle: bss_loss and CQM events. Handling these events synchronously is sufficient. Signed-off-by:

Since wfx_bss_params_work() does not exist anymore, there is no more reason to keep a copy of bss_params in struct wfx_dev. A local instance in wfx_join_finalize() is sufficient. Signed-off-by:

The firmware is able to filter beacons and send a notification if one or multiple beacons are not received. Note that it send this notification only once. Only if it receive beacons gain, it send a new notification. Currently, the driver handle the connection loss itself (see wfx_cqm_bssloss_sm()). It send null frames and watch the answers. This patch fixes all this mess: - settle firmware to send a notification on the first beacon loss - call ieee80211_beacon_loss() and let mac80211 handle all the process - since we do have notification for each beacon loss, add a period task that call ieee80211_beacon_loss() until we receive "REGAIN" notification. Thus, we can drop the ugly wfx_cqm_bssloss_sm() and wfx_bss_params_work(). Signed-off-by:
