wifi: mt76: do not run mt76_unregister_device() on unregistered hw

2024-10-17T13:21:29+00:00

commit 41130c32f3a18fcc930316da17f3a5f3bc326aa1 upstream. Trying to probe a mt7921e pci card without firmware results in a successful probe where ieee80211_register_hw hasn't been called. When removing the driver, ieee802111_unregister_hw is called unconditionally leading to a kernel NULL pointer dereference. Fix the issue running mt76_unregister_device routine just for registered hw.

wifi: mt76: mt7921s: fix potential hung tasks during chip recovery

2024-06-27T11:46:16+00:00

[ Upstream commit ecf0b2b8a37c8464186620bef37812a117ff6366 ] During chip recovery (e.g. chip reset), there is a possible situation that kernel worker reset_work is holding the lock and waiting for kernel thread stat_worker to be parked, while stat_worker is waiting for the release of the same lock. It causes a deadlock resulting in the dumping of hung tasks messages and possible rebooting of the device. This patch prevents the execution of stat_worker during the chip recovery.

wifi: mt76: fix broken precal loading from MTD for mt7915

2024-01-25T23:27:43+00:00

commit e874a79250b39447765ac13272b67ac36ccf2a75 upstream. Commit 495184ac91bb ("mt76: mt7915: add support for applying pre-calibration data") was fundamentally broken and never worked. The idea (before NVMEM support) was to expand the MTD function and pass an additional offset. For normal EEPROM load the offset would always be 0. For the purpose of precal loading, an offset was passed that was internally the size of EEPROM, since precal data is right after the EEPROM. Problem is that the offset value passed is never handled and is actually overwrite by offset = be32_to_cpup(list); ret = mtd_read(mtd, offset, len, &retlen, eep); resulting in the passed offset value always ingnored. (and even passing garbage data as precal as the start of the EEPROM is getting read) Fix this by adding to the current offset value, the offset from DT to correctly read the piece of data at the requested location.

wifi: mt76: mt7921: fix country count limitation for CLC

[ Upstream commit fa6ad88e023ddfa6c5dcdb466d159e89f451e305 ] Due to the increase in the number of power tables for 6Ghz on CLC, the variable nr_country is no longer sufficient to represent the total quantity. Therefore, we have switched to calculating the length of clc buf to obtain the correct power table. Additionally, the version number has been incremented to 1.
