Subject: Re: [v3,33/36] genirq: Use helper function to access
 irq_data->msi_desc

Say thanks to the people who mindlessly fiddled in the core managed
fields of irqdesc and irqdata. The hard to track down wreckage they
caused me to enforce accessors.

The new accessors are to help migrating members of irq_data to a new
data structure without breaking the world and some more.

Thanks,
