wifi: mt76: mt7915: mcu: increase eeprom command timeout

2025-08-20T16:36:08Z

[ Upstream commit efd31873cdb3e5580fb76eeded6314856f52b06e ] Increase the timeout for MCU_EXT_CMD_EFUSE_BUFFER_MODE command. Regular retries upon hardware-recovery have been observed. Increasing the timeout slightly remedies this problem.

wifi: mt76: mt7915: mcu: re-init MCU before loading FW patch

2025-08-20T16:36:08Z

[ Upstream commit ac9c50c79eaef5fca0f165e45d0c5880606db53e ] Restart the MCU and release the patch semaphore before loading the MCU patch firmware from the host. This fixes failures upon error recovery in case the semaphore was previously taken and never released by the host. This happens from time to time upon triggering a full-chip error recovery. Under this circumstance, the hardware restart fails and the radio is rendered inoperational.

Currently, mt7925_thermal_init() does not check for this case, which results in a NULL pointer dereference. Add NULL check after devm_kasprintf() to prevent this issue.
