Subject: [PATCH 073/552] ARM: Activate FIQs to avoid __irq_startup warnings
|
|
|
|
There is a new test in __irq_startup that the IRQ is activated, which
|
|
hasn't been the case for FIQs since they bypass some of the usual setup.
|
|
|
|
Augment enable_fiq to include a call to irq_activate to avoid the
|
|
warning.
