Hi,
Adding Tomi to Cc.

Yeah disabling lockdep by removing PROVE_LOCKING from omap2plus_defconfig
makes n900 LCD work for me again. Not getting any lockdep warnings
during boot with lockdep enabled though. So basically the following
patch makes LCD work on n900 with omap2plus_defconfig.
Tomi, got any ideas?

During idle, both should go off and are doing so for me. Both LEDs off
indicates off mode, left LED off is for retention mode. So you still
have something blocking off mode, maybe check:
echo 1 > /sys/kernel/debug/pm_debug/enable_off_mode
Regards,
Tony
