Subject: [PATCH 4/5] [media] staging: lirc_bt829: remove
This driver is for an old mach64 VT board, which also has a framebuffer
driver (atyfb) and userspace mach64 X driver.
It was merged in 2010 and noone has attempted to port it to rc-core,
which would be necessary to get it out of staging.
I have not been able to track down the hardware either.
