Subject: [PATCH v2 1/2] Bluetooth: hci_qca: Rename STATE_<flags> to QCA_<flags>
Date: Tue, 12 Mar 2019 13:42:21 -0700	[thread overview]
Message-ID: <CAG5bF+RLTaYbrn8uSpoU+W=PBmNawR6Ov0EOEcfuSymzuini5w@mail.gmail.com> (raw)
In-Reply-To: <20190312204217.73296-1-mka@chromium.org>

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@chromium.org>

Changes in v2:
- don't use BIT()
