Subject: ath9k: fix ath9k_hw_gpio_get() to return 0 or 1 on success

From: Matthias Schiffer <[email protected]>

commit 91851cc7a939039bd401adb6ca3da4402bec1d0c upstream.

Commit b2d70d4944c1 ("ath9k: make GPIO API to support both of WMAC and SOC") refactored ath9k_hw_gpio_get() to support both WMAC and SOC GPIOs, changing the return on success from 1 to BIT(gpio). This broke some callers like ath_is_rfkill_set(). This doesn't fix any known bug in mainline at the moment, but should be fixed anyway.

Instead of fixing all callers, change ath9k_hw_gpio_get() back to only return 0 or 1.
