media: lirc: remove LIRCCODE and LIRC_GET_LENGTH 



LIRCCODE is a lirc mode where a driver produces driver-dependent
codes for receive and transmit. No driver uses this any more. The
LIRC_GET_LENGTH ioctl was used for this mode only.

``LIRC_MODE_LIRCCODE``



    This mode can be used for IR receive and send.



    The IR signal is decoded internally by the receiver, or encoded by the

    transmitter. The LIRC interface represents the scancode as byte string,

    which might not be a u32, it can be any length. The value is entirely

    driver dependent. This mode is used by some older lirc drivers.



    The length of each code depends on the driver, which can be retrieved

    with :ref:`lirc_get_length`. This length is used both

    for transmitting and receiving IR.

*********************

ioctl LIRC_GET_LENGTH

*********************



Name

====



LIRC_GET_LENGTH - Retrieves the code length in bits.



Synopsis

========



.. c:function:: int ioctl( int fd, LIRC_GET_LENGTH, __u32 *length )

    :name: LIRC_GET_LENGTH



Arguments

=========



``fd``

    File descriptor returned by open().



``length``

    length, in bits





Description

===========



Retrieves the code length in bits (only for

:ref:`LIRC_MODE_LIRCCODE <lirc-mode-lirccode>`).

Reads on the device must be done in blocks matching the bit count.

The bit could should be rounded up so that it matches full bytes.





Return Value

============



On success 0 is returned, on error -1 and the ``errno`` variable is set

appropriately. The generic error codes are described at the

:ref:`Generic Error Codes <gen-errors>` chapter.
