When booting Nokia N900 smartphone with v3.12 + omap2plus_defconfig
(LOCKDEP enabled) and CONFIG_DISPLAY_PANEL_SONY_ACX565AKM enabled,
the following BUG is seen during the boot:
[ 7.302154] ==================[ 7.307128] [ BUG: bad unlock balance detected! ]
[ 7.312103] 3.12.0-los.git-2093492-00120-g5e01dc7 #3 Not tainted
[ 7.318450] -------------------------------------
[ 7.323425] kworker/u2:1/12 is trying to release lock (&ddata->mutex) at:
[ 7.330657] [<c031b760>] acx565akm_enable+0x12c/0x18c
[ 7.335998] but there are no more locks to release!
Fix by removing the extra mutex_unlock().

Hm why would you fix it like this? Why not remove the mutex_unlock from
acx565akm_panel_power_on()? Looks to me like that one is the buggy one.

The unlock needs to be there because acx565akm_bl_update_status()
also locks the mutex. I'll send a new version where the mutex_lock()
is done inside acx565akm_panel_power_on().

Commit c37dd677988ca50bc8bc60ab5ab053720583c168 fixes the unbalanced
unlock in acx565akm_enable but introduces another problem - if
acx565akm_panel_power_on exits early, the mutex is not unlocked. Fix
that by unlocking the mutex on early return. Also add mutex protection in
acx565akm_panel_power_off and remove an unused variable

Hmm, I introduced a bug with that patch (recursive lock), will send a
new version that fixes it

I think this is just getting more messy. How about we more or less revert the c37dd677988ca50bc8bc60ab5ab053720583c168 and fix it like this:

The patch does not apply cleanly on top of rc7, however I applied it by
hand. So far it seems it fixes the issue brought by
c37dd677988ca50bc8bc60ab5ab053720583c168, though I didn't test if
mutex_lock/mutex_unlock are complementary in every code path (at least
not explicitly, I guess maemo is doing it for us anyway :) ).
So, shall I send a patch incorporating your code changes, or you will do it?
Regards,
Ivo
