Lorenzo BianconiandFelix Fietkau 3598046d01 mt76: mmio: introduce mt76x02_check_tx_hang watchdog
Port mt76x02_check_tx_hang watchdog from vendor driver in order to
perform a device reset when tx mac/dma logic hangs. Tx mac/dma stuck
has been observed when the device is heavy loaded or in a noisy
environment. Moreover introduce wdt delayed work in order to run
tx_hang watchdog. For the moment run mt76x02_check_tx_hang watchdog
just on mt76x2 devices since the issue has not been observed on mt76x0
driver yet

Weijie GaoandFelix Fietkau 8178f0d2ce mt7603: apply efuse data only when it exists
Some mt7603e chip has empty efuse data.
In this case driver will crash due to dereferencing NULL pointer.

The mt7603_eeprom_load will return success directly if the chip has no efuse
data and dev->mt76.otp.data is left empty, i.e. NULL pointer.
The mt7603_eeprom_init will then try to dereference dev->mt76.otp.data
without checking its value.

This patch adds a check around these codes to prevent kernel panic.
