3.3-stable review patch. If anyone has any objections, please let me know. ------------------ From: Gabor Juhos <redacted> commit de14ca6ae2c592d66db88f1e5596b26f7f011384 upstream. The current code puts the built-in WMAC device of the AR933X SoCs into reset instead of starting it. This causes a hard lock on AR933X based boards when the wireless driver tries to access the device.
