TODO RC

Investigation needed:

• struct ir_raw_event_ctrl member prev_ev. Investigate if this can be removed.
• serial_ir tx w/ softcarrier, does it work on 32 bit? "new_duty_cycle * NSEC_PER_SEC" > 2^32.
• Kconfig RC_CORE should not depend on MEDIA_SUPPORT
• depends on RC_COREC -> select RC_CORE, depends on INPUT?
• RC device RC_DRIVER_IR_RAW_TX leaks dev->raw on rc_unregister_device()?
• Unplug iguanair with lirc chardev open causes kernel to go bang
• Compile kernel with KASAN. mceusb says:

[ 56.365080] BUG: KASAN: slab-out-of-bounds in mceusb_dev_printdata+0xdc/0x830 [mceusb] at addr ffff8801df071d0a

• saa7134 should add trailing space (timeout handling). Once this is fixed, implement the following item.
• ir_raw_event_store_edge() should not use REP_DELAY.

Worked needed:

• ir-spi says "Unspecified device" in dmesg since ir-spi does not set input_name; rename input_name to device_name for all RC devices.
• pwm gpio transmitter needed (Sean Young working on this)
• bitbang gpio transmitter needed (Sean Young working on this)
• lirc_zilog rc core driver (Sean Young working on this)
• Once lirc_zilog is removed, remove lirc kapi.

ir-keytable changes needed.

• Cannot list RC core devices if one of them is of type RC_DRIVER_IR_RAW_TX
• Without CONFIG_INPUT_EVDEV ir-keytable goes bang
• "ir-ctl -S rc6_mce:0x800f0410" does not work on 32-bit
