Relative measurements are typically between 0 and 0xffff. However,
for some tuners (TUNER_S7395 and TUNER_S0194), the range were from
0 to 0xff00, with means that 100% is never archived.
Also, TUNER_RS2000 uses a more complex math.

So, create a macro that does the conversion using bit operations
and use it for all conversions.

The code is also easier to read with is a bonus.

Cleanup this sparse warning:

Both c_tmp and s_tmp actually stores a u16 stat. Using a u64 data
there is a waste, specially on u32 archs, as 64 ints there are more
expensive.

So, change the types to u32 and do the typecast only when storing
the result.

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.

Create dm04_read_status to check lock through either interrupt values
or directly by the call back.

When the device is not streaming the frontends original call back is
used. When streaming has started it turns off I2C messaging by
setting st->i2c_talk_onoff to zero. I2C can only be turn on again
by one of the other allowed frontend calls.

All old code is removed from lme2510_msg and this function only needs
to set st->i2c_talk_onoff to 1.

The lock status is saved and when the frondend is locked is maintained
by lme2510_int_response who will now just kill the lock.

The call back for rs2000 tuner is nologer required.

All frontend types have been tested.

Right now the protocol information is not preserved, rc-core gets handed a
scancode but has no idea which protocol it corresponds to.

This patch (which required reading through the source/keymap for all drivers,
not fun) makes the protocol information explicit which is important
documentation and makes it easier to e.g. support multiple protocols with one
decoder (think rc5 and rc-streamzap). The information isn't used yet so there
should be no functional changes.

Remove last_key and key_timeout and use jiffies plus 60ms

If the current jiffies is time_after the interrupt urb overdue and

drivers/media/usb/dvb-usb-v2/lmedm04.c:802:13: warning: no previous prototype for 'lme_firmware_switch' [-Wmissing-prototypes]
Signed-off-by: NMauro Carvalho Chehab <mchehab@redhat.com>

The RC_TYPE_* defines are currently used both where a single protocol is
expected and where a bitmap of protocols is expected.

Functions like rc_keydown() and functions which add/remove entries to the
keytable want a single protocol. Future userspace APIs would also
benefit from numeric protocols (rather than bitmap ones). Keytables are
smaller if they can use a small(ish) integer rather than a bitmap.

Other functions or struct members (e.g. allowed_protos,
enabled_protocols, etc) accept multiple protocols and need a bitmap.

Using different types reduces the risk of programmer error. Using a
protocol enum whereever possible also makes for a more future-proof
user-space API as we don't need to worry about a sufficient number of
bits being available (e.g. in structs used for ioctl() calls).

The use of both a number and a corresponding bit is dalso one in e.g.
the input subsystem as well (see all the references to set/clear bit when
changing keytables for example).

This patch separate the different usages in preparation for
upcoming patches.

Where a single protocol is expected, enum rc_type is used; where one or more
protocol(s) are expected, something like u64 is used.

The patch has been rewritten so that the format of the sysfs "protocols"
file is no longer altered (at the loss of some detail). The file itself
should probably be deprecated in the future though.
