2fd7f398d3 [media] media: rc: gpio-ir-recv: add support for device tree parsing
This patch adds device tree parsing for gpio_ir_recv platform_data and
the mandatory binding documentation. It basically follows what we already
have for e.g. gpio_keys. All required device tree properties are OS
independent but an optional property allows linux specific support for rc
maps.

4c62e9764a Drivers: media: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

bbe2a1d32f [media] rc: Fix double free in gpio_ir_recv_remove()
Since rc_unregister_device() frees its argument there's no need to
subsequently call rc_free_device() on the same variable - in fact it's
a double free bug.
Easily fixed by just removing the rc_free_device() call.

e5d85b9ac3 [media] rc: Fix double free in gpio_ir_recv_probe()
At the 'err_request_irq' label, rc_unregister_device(rcdev) frees its
argument. So when we fall through to the 'err_gpio_request' label
further down and call rc_free_device(rcdev) then that's a double free.
Fix that by moving 'rcdev = NULL' from after the call to
rc_free_device() to after rc_unregister_device(). That fixes the
problem since rc_free_device() just does nothing if passed NULL and
there's no further use of 'rcdev' after the call to rc_free_device()
so it's not needed there.

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.

955b44304a [media] gpio-ir-recv: a couple signedness bugs
There are couple places where we check unsigned values for negative.  I
changed ->gpin_nr to signed because in gpio_ir_recv_probe() we do:
        if (pdata->gpio_nr < 0)
                return -EINVAL;
I also change gval to a signed int in gpio_ir_recv_irq() because that's
the type that gpio_get_value_cansleep() returns and we test for negative
returns.
