[PATCH v2 1/2] Bluetooth: hci_qca: Rename STATE_<flags> to QCA_<flags>

From: Matthias Kaehlcke
Date: Tue Mar 12 2019 - 16:42:40 EST


Rename STATE_IN_BAND_SLEEP_ENABLED to QCA_IN_BAND_SLEEP_ENABLED.
The constant represents a flag (multiple flags can be set at once),
not a unique state of the controller or driver.

Also make the flag an enum value instead of a pre-processor constant
(more flags will be added to the enum group by another patch).

Signed-off-by: Matthias Kaehlcke <mka@xxxxxxxxxxxx>

Changes in v2:
