Hi Daniel,
I think we must unlock the master spinlock even
prcmu_gic_decouple function now always return 0.
Could you give some infos about this?
Thanks.

I agree, that would be cleaner.
AFAICS, your patch does not solve the problem because 'recouple' will be
false if prcmu_gic_decouple fails, so the lock will never be release.
That will be simpler to do:
if (prcmu_gic_decouple()) {
spin_unlock(&master);
goto out;
}
no ?

Hi Daniel,
Happy new year, Thank you for reply.
Sorry for that i have refer the old patch email.
I have updated the patch, Pls check the URL:
http://lists.infradead.org/pipermail/linux-arm-kernel/2012-December/138939.html
Now i am using gmail GUI tools to send mail, i will switch email tool
to MUTT to commit the other patchs in the future.

Ok.
Please do not introduce a new variable which is at the end pointless and
add more complexity.
You can simply remove the if statement for prcmu_gic_decouple(), or
unlock if it fails.
Thanks
