sony-laptop: Make the driver use MSC_SCAN and a setkeycode and getkey…
Browse files Browse the repository at this point in the history 
…code key table.

The following is the only way I could think of to hide some events as
per Dmitry suggestions while still using the default {set,get}keycode
implementation.

Make the driver use MSC_SCAN and a setkeycode and getkeycode key table.
