In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly.

|
|
* - MCIR-2 32-bit IR signals used for standard keyboard keys

*
|

* The media keys on the keyboard send RC-6 signals that are indistinguishable

|
|
