2023-12-11wifi: mt76: mt7921: reduce the size of MCU firmware download Rx queueSean Wang2-2/+3
We actually don't need the reserve the 512 entries for the MCU firmware download Rx queue because the queue was only used in the firmware download phase to save the most of space and the reduction can significantly help with reducing latency we spent by ~20% further in resetting the Rx queue as the device was waking up from deep sleep mode.

2023-12-07wifi: mt76: mt7921s: fix workqueue problem causes STA association failWang Zhao5-12/+18
The ieee80211_queue_work function queues work into the mac80211 local->workqueue, which is widely used for mac80211 internal work processes. In the mt76 driver, both the mt76-sido-status and mt76-sdio-net threads enqueue workers to the workqueue with this function. However, in some cases, when two workers are enqueued to the workqueue almost simultaneously, the second worker may not be scheduled immediately and may get stuck for a while. This can cause timing issues. To avoid these timing conflicts caused by worker scheduling, replace the worker with an independent thread.

2023-12-07wifi: mt76: Convert to platform remove callback returning voidUwe Kleine-König3-13/+6
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert the three mt76 drivers from always returning zero in the remove callback to the void returning variant.
