Hello Samuel, Linus or Lee,
This is to back-port to the stable-3.7. It skips the 2nd and 3rd chunks
due to cannot see it needed there. Can you please help ACK/NAK this?
Regards,
CAI Qian

Subject: [PATCH] mfd: db8500-prcmu: Fix irqdomain usage
This fixes two issues with the DB8500 PRCMU irqdomain:
- You have to state the irq base 0 to get a linear domain
for the DT case from irq_domain_add_simple()
- The irqdomain was not used to translate the initial irq
request using irq_create_mapping() making the linear
case fail as it was lacking a proper descriptor.
I took this opportunity to fix two lines of whitespace
errors in related code as I was anyway messing around with
it.
