- +Subject: [PATCH] ath9k: fix ath9k_hw_gpio_get() to return 0 or 1 on success
- +
- +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().
- +
- +Instead of fixing all callers, change ath9k_hw_gpio_get() back to only
- +return 0 or 1.
