Subject: media: lirc_sir: make device registration work
From: Jarod Wilson <[email protected]>
commit 4b71ca6bce8fab3d08c61bf330e781f957934ae1 upstream.
For one, the driver device pointer needs to be filled in, or the lirc core
will refuse to load the driver. And we really need to wire up all the
platform_device bits. This has been tested via the lirc sourceforge tree
and verified to work, been sitting there for months, finally getting
around to sending it. :\
