ba2d559b29 media: af9015: use af9013 demod pid filters
PID filters are moved to af9013 demod driver as those are property of
demod. As pid filters are now implemented correctly by demod driver,
we could enable pid filter support for possible slave demod too on
dual tuner configuration.

2ceeca0499 [media] rc: split nec protocol into its three variants
Currently we do not know what variant (bit length) of the nec protocol
is used, other than from guessing from the length of the scancode. Now
nec will be handled the same way as the sony protocol or the rc6 protocol;
one variant per bit length.

In the future we might want to expose the rc protocol type to userspace
and we don't want to be introducing this world of pain into userspace
too.

ef703f49a6 Eliminate bad hash multipliers from hash_32() and hash_64()
The "simplified" prime multipliers made very bad hash functions, so get rid
of them.  This completes the work of 689de1d6ca.

To avoid the inefficiency which was the motivation for the "simplified"
multipliers, hash_64() on 32-bit systems is changed to use a different
algorithm.  It makes two calls to hash_32() instead.

drivers/media/usb/dvb-usb-v2/af9015.c uses the old GOLDEN_RATIO_PRIME_32
for some horrible reason, so it inherits a copy of the old definition.

0df289a209 [media] dvb: Get rid of typedev usage for enums
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.

120703f9eb [media] rc-core: document the protocol type
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.

65e2f1cb3f [media] af9015: Don't use dynamic static allocation
Dynamic static allocation is evil, as Kernel stack is too low, and
compilation complains about it on some archs:
	drivers/media/usb/dvb-usb-v2/af9015.c:433:1: warning: 'af9015_eeprom_hash' uses dynamic stack allocation [enabled by default]
In this specific case, it is a gcc bug, as the size is a const, but
it is easy to just change it from const to a #define, getting rid of
the gcc warning.

c003ab1bed [media] rc-core: add separate defines for protocol bitmaps and numbers
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.
