Patch 9/9:
It seems ->irq_on and ->irq_off are now only wrapped by freeze()/thaw() and unused elsewhere.
This patch
- Remove ->irq_on and ->irq_off.
- Rename ->freeze and ->thaw to irq_on() and irq_off() to be specific.
Hopefully the LLDDs need to implement only one irq on/off by either host adapter masking,
nIEN manipulation, or both or something else.
No patch for this yet. Just some idea like below...
