I have tried this patch, while it initially got MythTV working, there is
too many call backs and some failed to acquire the lock. The device
became unstable on both single and dual devices.
The callbacks
af9015_af9013_read_status,
af9015_af9013_init
af9015_af9013_sleep
had to be removed.
I take your point, a call back can be an alternative.
The patch didn't stop the firmware fails either.
The af9015 usb bridge on the whole is so unstable in its early stages,
especially on a cold boot and when the USB controller has another device
on it, such as card reader or wifi device.
I am, at the moment looking to see if the fails are due to interface 1
being claimed by HID.
I just got af9013 rewrite ready. Feel free to test.

It reduces typical statistics polling load maybe 1/4 from the original.
I see still small glitch when switching to channel. That seems to come
from tuner driver I2C load. There is 3 tuners used for dual devices;
MXL5005S, MXL5007T and TDA18271. I have only MXL5005S and MXL5007T dual
devices here. MXL5005S is worse than MXL5007T but both makes still
rather much I/O.
