wifi: mt76: fix the issue of missing txpwr settings from ch153 to ch177

2024-03-26T22:18:19Z

[ Upstream commit e9a46175a79fbc591c48d433020444b8fa2750ee ] Because the number of channels to be configured is calculated using the %, and it results in 0 when there's an exact division, this leads to some channels not having their tx power configured.

wifi: mt76: mt792x: fix a potential loading failure of the 6Ghz channel config from ACPI

2024-03-26T22:18:19Z

[ Upstream commit 07ce1d46372489d90f9cccebb3277d1af801c4b9 ] In some case, the MTCL table will exist, but MTDS table will not. So the SAR will init fail. This patch make MTCL and MTDS can exist with no dependence.

wifi: mt76: mt7925e: fix use-after-free in free_irq()

2024-03-26T22:18:19Z

[ Upstream commit a5a5f4413d91f395cb2d89829d376d7393ad48b9 ] From commit a304e1b82808 ("[PATCH] Debug shared irqs"), there is a test to make sure the shared irq handler should be able to handle the unexpected event after deregistration. For this case, let's apply MT76_REMOVED flag to indicate the device was removed and do not run into the resource access anymore.
