There are lots of typedefs there. Let's get rid of them.
Most of the work here is due to this small script:
if [ "$3" == "" ]; then
echo "usage: $0 type DRXName drx_name"
fi
t=$1; f=$2; g=$3
for i in *.[ch]; do
sed s,"p${f}_t","$t $g *",g <$i >a && mv a $i && \
sed s,"${f}_t","$t $g",g <$i >a && mv a $i
done
Just kept there the function typedefs, as those are still useful.
Yet, all those tuner_ops can likely be just removed on a latter

Implement em28xx_usb_driver suspend, resume, and reset_resume hooks.
These hooks will invoke em28xx core em28xx_suspend_extension() and
em28xx_resume_extension() to suspend and resume registered extensions.
Approach:
Add power management support to em28xx usb driver. This driver works in
conjunction with extensions for each of the functions on the USB device
for video/audio/dvb/remote functionality that is present on media USB
devices it supports. During suspend and resume each of these extensions
will have to do their part in suspending the components they control.
Adding suspend and resume hooks to the existing struct em28xx_ops will
enable the extensions the ability to implement suspend and resume hooks
to be called from em28xx driver. The overall approach is as follows:
-- add suspend and resume hooks to em28xx_ops
-- add suspend and resume routines to em28xx-core to invoke suspend
and resume hooks for all registered extensions.
-- change em28xx dvb, audio, input, and video extensions to implement
em28xx_ops: suspend and resume hooks. These hooks do what is necessary
to suspend and resume the devices they control.

Restructure the way we bring the various GPIOs out of reset. In particular:
1. we only need to setup the GPIOs as outputs once
2. there's no point in writing 0x40 to register 0x00 since that's the EEPROM
write protect and already it's configured as an input
3. Separate out the act of enabling the power supply and bringing the tuner
and demod out of reset. If you don't then the chip may not be properly
enabled (as the power supply is still ramping up when the chip comes
out of reset). This can result in probing failures.

Add m88rs2000_get_tune_settings, min delay of 2000 ms on symbol
rate more than 3000000 and delay of 3000ms less than this.
Adding min delay prevents crashing the frontend on continuous
transponder scans. Other dvb_frontend_tune_settings remain as default.
This makes very little time difference to good channel scans, but slows down
the set frontend where lock can never be achieved i.e. DVB-S2.
