-Driver general quality is not good enough for mainline. Also, other
-device drivers (USB-bridge, tuner) needed for Astrometa receiver in
-question could need some changes. However, if that driver is mainlined
-due to some other device than Astrometa, unrelated TODOs could be
-skipped. In that case rtl28xxu driver needs module parameter to prevent
-driver loading.
-
-Required TODOs:
-* missing lock flags
-* I2C errors
-* tuner sensitivity
-
-*Do not* send any patch fixing checkpatch.pl issues. Currently it passes
-checkpatch.pl tests. I don't want waste my time to review this kind of
-trivial stuff. *Do not* add missing register I/O error checks. Those are
-missing for the reason it is much easier to compare I2C data sniffs when
-there is less lines. Those error checks are about the last thing to be added.
-
-Patches should be submitted to:
-linux-media@vger.kernel.org and Antti Palosaari <crope@iki.fi>
