fd044de30b media: mceusb: Include three Hauppauge USB dvb device with IR rx
The three following Hauppauge USB DVB devices have IR receivers, but
lacked the support in mceusb to enable it:
- WinTV-HVR-935C
- WinTV-HVR-955Q
- WinTV-HVR-975

Tested HVR-955Q and HVR-975 plus RC5 remote and irw, works as intended.

183e19f5b9 media: rc: Remove init_ir_raw_event and DEFINE_IR_RAW_EVENT macros
This can be done with c99 initializers, which makes the code cleaner
and more transparent. It does require gcc 4.6, because of this bug
in earlier versions:

	https://gcc.gnu.org/bugzilla/show_bug.cgi?id=10676

Since commit cafa0010cd ("Raise the minimum required gcc version to
4.6"), this is the case.

279c60fd89 media: mceusb: add IR learning support features (IR carrier frequency measurement and wide-band/short-range receiver)
Windows Media Center IR transceivers include two IR receivers;
wide-band/short-range and narrow-band/long-range. The short-range
(5cm distance) receiver is for IR learning and has IR carrier
frequency measuring ability.

Add mceusb driver support to select the short range IR receiver
and enable pass through of its IR carrier frequency measurements.

RC and LIRC already support these mceusb driver additions.

rc rc0: Unspecified device as /devices/platform/soc/3f215080.spi/spi_master/spi32766/spi32766.128/rc/rc0

"Unspecified device" refers to input_name, which makes no sense for IR
TX only devices. So, rename to device_name.

Also make driver_name const char* so that no casts are needed anywhere.

Fault simulation/injection is by executing the following USB operation

    retval = usb_control_msg(ir->usbdev, usb_sndctrlpipe(ir->usbdev, 0),
	USB_REQ_SET_FEATURE, USB_RECIP_ENDPOINT,
	USB_ENDPOINT_HALT, usb_pipeendpoint(ir->pipe_out),
	NULL, 0, USB_CTRL_SET_TIMEOUT);
    dev_dbg(ir->dev, "set halt retval, %d", retval);

After setting halt state for the TX endpoint, perform an lirc "irsend"
to generate TX traffic to device. After the TX HALT, the patch restores
subsequent TX to working state.

0f7499fddb [media] rc-main: assign driver type during allocation
The driver type can be assigned immediately when an RC device
requests to the framework to allocate the device.

This is an 'enum rc_driver_type' data type and specifies whether
the device is a raw receiver or scancode receiver. The type will
be given as parameter to the rc_allocate_device device.

Change accordingly all the drivers calling rc_allocate_device()
so that the device type is specified during the rc device
allocation. Whenever the device type is not specified, it will be
set as RC_DRIVER_SCANCODE which was the default '0' value.

25ec587c02 [media] rc: don't break long lines
Due to the 80-cols restrictions, and latter due to checkpatch
warnings, several strings were broken into multiple lines. This
is not considered a good practice anymore, as it makes harder
to grep for strings at the source code.

As we're right now fixing other drivers due to KERN_CONT, we need
to be able to identify what printk strings don't end with a "\n".
It is a way easier to detect those if we don't break long lines.

So, join those continuation lines.

The patch was generated via the script below, and manually
adjusted if needed.

e947d9ad8a [media] mceusb: fix usbdev leak
mceusb_init_rc_dev() does usb_get_dev(), but there is no any
usb_put_dev() in the driver.

The patch tries to straighten logic. It moves usb_get_dev()
directly to mceusb_dev_probe() and adds usb_put_dev() to an error path
and to mceusb_dev_disconnect().

Found by Linux Driver Verification project (linuxtesting.org).

5b8c8d4191 [media] mceusb: select default keytable based on vendor
Some vendors have their on keymap table that are used on
all (or almost all) models for that vendor.

So, instead of specifying the keymap table per USB ID,
let's use the Vendor ID's table by default.

At the end, this will mean less code to be added when newer
devices for those vendors are added.

Of course, if rc_map is specified per board, it takes
precedence.

c5540fbb9d [media] rc-core: remove protocol arrays
The basic API of rc-core used to be:

	dev = rc_allocate_device();
	dev->x = a;
	dev->y = b;
	dev->z = c;
	rc_register_device();

which is a pretty common pattern in the kernel, after the introduction of
protocol arrays the API looks something like:

	dev = rc_allocate_device();
	dev->x = a;
	rc_set_allowed_protocols(dev, RC_BIT_X);
	dev->z = c;
	rc_register_device();

There's no real need for the protocols to be an array, so change it
back to be consistent (and in preparation for the following patches).

0cacb46ace [media] fix mceusb endpoint type identification/handling
Change the I/O endpoint handling of the mceusb driver to respect the endpoint
type reported by device (bulk/interrupt), rather than treating all endpoints
as type interrupt, which breaks devices using bulk endpoints when connected
to a xhci controller.  Accordingly, change the function calls to initialize
an endpoint's transfer pipe and urb handlers to use the correct function based
on the endpoint type.

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.
