[ Upstream commit 7c48662b9d56666219f526a71ace8c15e6e12f1f ]
The problem is that gpio_free() can sleep and the cfg_soc() can be
called with spinlocks held. One problematic call tree is:
--> ath_reset_internal() takes &sc->sc_pcu_lock spin lock
--> ath9k_hw_reset()
--> ath9k_hw_gpio_request_in()
--> ath9k_hw_gpio_request()
--> ath9k_hw_gpio_cfg_soc()
Remove gpio_free(), use error message instead, so we should make sure
there is no GPIO conflict.
Also remove ath9k_hw_gpio_free() from ath9k_hw_apply_gpio_override(),
as gpio_mask will never be set for SOC chips.
