[media] staging: remove todo and replace with lirc_zilog todo

The lirc_zilog driver is the last remaining lirc driver, so the existing
todo is no longer relevant.

-- All drivers should either be ported to ir-core, or dropped entirely
-  (see drivers/media/IR/mceusb.c vs. lirc_mceusb.c in lirc cvs for an
-  example of a previously completed port).
-
-- lirc_bt829 uses registers on a Mach64 VT, which has a separate kernel
-  framebuffer driver (atyfb) and userland X driver (mach64).  It can't
-  simply be converted to a normal PCI driver, but ideally it should be
-  coordinated with the other drivers.

+1. Both ir-kbd-i2c and lirc_zilog provide support for RX events for
+the chips supported by lirc_zilog.  Before moving lirc_zilog out of staging:
+
+a. ir-kbd-i2c needs a module parameter added to allow the user to tell
+   ir-kbd-i2c to ignore Z8 IR units.
+
+b. lirc_zilog should provide Rx key presses to the rc core like ir-kbd-i2c
+   does.
+
+
+2. lirc_zilog module ref-counting need examination.  It has not been
+verified that cdev and lirc_dev will take the proper module references on
+lirc_zilog to prevent removal of lirc_zilog when the /dev/lircN device node
+is open.
+
+(The good news is ref-counting of lirc_zilog internal structures appears to be
+complete.  Testing has shown the cx18 module can be unloaded out from under
+irw + lircd + lirc_dev, with the /dev/lirc0 device node open, with no adverse
+effects.  The cx18 module could then be reloaded and irw properly began
+receiving button presses again and ir_send worked without error.)
+
+
+3. Bridge drivers, if able, should provide a chip reset() callback
+to lirc_zilog via struct IR_i2c_init_data.  cx18 and ivtv already have routines
+to perform Z8 chip resets via GPIO manipulations.  This would allow lirc_zilog
+to bring the chip back to normal when it hangs, in the same places the
+original lirc_pvr150 driver code does.  This is not strictly needed, so it
+is not required to move lirc_zilog out of staging.
+
+Note: Both lirc_zilog and ir-kbd-i2c support the Zilog Z8 for IR, as programmed
+and installed on Hauppauge products.  When working on either module, developers
+must consider at least the following bridge drivers which mention an IR Rx unit
+at address 0x71 (indicative of a Z8):
