2020-12-10iwlwifi: mvm: do more useful queue sync accountingJohannes Berg
We're currently doing accounting on the queue sync with an atomic variable that counts down the number of remaining notifications that we still need. As we've been hitting issues in this area, modify this to track a bitmap of queues, not just the number of queues, and print out the remaining bitmap in the warning.

2020-12-10iwlwifi: mvm: fix 22000 series driver NMIJohannes Berg
For triggering an NMI in the firmware, we should only set BIT(24) in the corresponding register, not the entire mask that's usable by the driver. This currently doesn't matter because the firmware only enables BIT(24), but we'll start using BIT(25) for other purposes with an upcoming API change.

2020-12-10iwlwifi: mvm: clear up iwl_mvm_notify_rx_queue() argument typeJohannes Berg
The argument type to iwl_mvm_notify_rx_queue() is currently just a u8 *, but that's misleading because we actually need the inner data to be of type struct iwl_mvm_internal_rxq_notif, because we interpret it when we get it back from the device (to check the sync bool and possibly the cookie.) Therefore, clear up any potential confusion and require that the data passed is of type struct iwl_mvm_internal_rxq_notif *. Also, while at it, rename the "count" to "notif_size" as "count" doesn't really clearly say what it's counting.

2020-12-10iwlwifi: pcie: remove obsolete pre-release support codeEmmanuel Grumbach
We no longer need code that was introduced to differentiate between two early versions of 8260. We can remove this convoluted way to get the hardware version that was needed because of a bug in the register's configuration. Moreover, since we no longer need to access the PRPH registers, we no longer need to wake up the device, request ownership, etc... Remove all that.

The vrf_add_mac_header_if_unset() is defined within a conditional compilation block which depends on the CONFIG_IPV6 macro. However, the vrf_add_mac_header_if_unset() needs to be called also by IPv4 related code and when the CONFIG_IPV6 is not set, this function is missing. As a consequence, the build process stops reporting the error: ERROR: implicit declaration of function 'vrf_add_mac_header_if_unset' The problem is solved by *only* moving functions vrf_add_mac_header_if_unset() and vrf_prepare_mac_header() out of the conditional block.

2020-12-09uio: uio_hv_generic: use devm_kzalloc() for private data allocAlexandru Ardelean
This is a minor cleanup for the management of the private object of this driver. The allocation can be tied to the life-time of the hv_device object. This cleans up a bit the exit & error paths, since the object doesn't need to be explicitly free'd anymore.
