The driver is initialized several times. This is wrong and if the return code of the function was checked, it will return -EINVAL.
Move this initialization out of the loop.

Fix for this is already and v2 of the patch is here [1]
Ah, ok. Thanks for reviewing the patch.
Can we find a solution to have a single entry point to sumbit patches for all the cpuidle drivers ?
Otherwise, consolidating them is a pain: a patch for the samsung tree, another one for the at91 tree, etc ... and wait for all the trees to sync before continuing to consolidate the code.
Wouldn't be worth to move these drivers under the PM umbrella instead of the SoC specific code ?
Any idea to simplify the cpuidle consolidation and maintenance ?
Fisrtly patches get posted to right mailing list based on where the code resides. So one must keep a watch on LAKML for the patches.
Yes, I agree.
The main issue is the multiple tree for the different drivers making hard to track, modify and improve the drivers in one shot.
It is not the first time, a modification of the cpuidle framework implied to modify all the drivers.
When Rob introduced the first code consolidation, that took months to add a simple flag in the drivers because we had to wait for the merge before the changes in drivers/cpuidle/cpuidle.c were visible.
Talking specific to OMAP idle code, there is plan to move to drivers/idle/* but for that to happen there are some PRM/CM dependency for which also driver movement is planned. Once that happen, OMAP idle will find its way in drivers/idle/*
That would be *really* great. If we can do that for all the drivers, that will solve the multi-location / multi-tree problem.
The u8500 driver will be moved soon to this directory also.
I did some modifications around the at91 some months ago to encapsulate the code more, maybe it could be also a good candidate. Nicolas ?
For OMAP3 that could be a bit more difficult. Who is maintaining the driver now ?
I Cc'ed the different maintainers for the other boards, may be they can react ?
Thanks -- Daniel
