The DVB API was originally defined using typedefs. This is against
Kernel CodingStyle, and there's no good usage here. While we can't
remove its usage on userspace, we can avoid its usage in Kernelspace.
So, let's do it.
This patch was generated by this shell script:
for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done
While here, make CodingStyle fixes on the affected lines.

call "release_firmware"
GIT_AUTHOR_DATE=1416472432
The release_firmware() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.

By reading the comment, it is said that BER should be calculated as:

There are large chunks of code at drx-j that aren't used. Most
of them are due to analog TV support. Well, just enabling them
won't make analog support work, as devices with DRX and analog
support requires an extra chip (avf4910).
We don't have drivers for it, nor the current device that uses
this frontend has support for analog TV.
So, let's just get rid of this code. If latter needed, this
patch can easily be reverted from git history.

QAM/256 currently doesn't work, as the code is only called if
channel->mirror is DRX_MIRROR_AUTO, but a prevous if prevents
this condition to happen.
While here, returns -EINVAL to not supported QAM modes and
simplify the code, reducing the number of indents.

Checking if a time is after another one can have issues, as
times are generally u32 wide.
Use the proper macros for that at scu_command().
It should be noticed that other places also use jiffies
calculus on an improper way. This should be fixed too,
but the logic there is more complex. So, let's do it in
separate patches.

Modulation and other parameters might have changed. So, better
to call ctrl_set_standard() even if the device is already
powered.
That helps to put the device into a sane state, if something
got wrong on a previous set_frontend call.

When switching from one video standard to another one,
power_down_vsb is called twice. Well, as the device is already
in power_down mode, the second call always fail. This causes that
any subsequent frontend set to fail as well:

provided by the tuner, with can be different for QAM and

This file does an ugly binding between drxj and DVB frontend.
Remove most of the functions there. We still need to get rid of
get_frequency and set_frequency, but such patch is a little more
complex, as it should also remove some previous tuner bindings.
