"get" is an action verb and usually action verbs return error codes. removing "get" makes them predicates which normally return bool. And based upon the usage, IMO they become even better as: ath12k_acpi_rfkill_disabled() ath12k_acpi_11be_disabled() Since then they work very well in 'if' statements > + > int ath12k_acpi_start(struct ath12k_base *ab) > { > acpi_status status;

Currently, ath12k does not support enable or disable specific features by ACPI bitflag. To address this issue, obtain the ACPI bitflag value and use it to selectively enable or disable specific features. This patch will not affect QCN9274, because only WCN7850 supports ACPI.
