irqchip\/ast2700-intc: Avoid allocating in the irq_domain activate() callback<\/p>\n
The interrupt core calls the irq_domain_activate() callback from
\n__setup_irq() with desc->lock held and interrupts disabled. Both
\naspeed_intc1_irq_domain_activate() and aspeed_intc0_resolve_route() test a
\ncompatible string with fwnode_device_is_compatible().<\/p>\n
fwnode_device_is_compatible() invokes fwnode_property_match_string(), which
\nallocates with GFP_KERNEL. That’s obviously not possible with interrupts
\ndisabled and a raw spinlock held.<\/p>\n
Both call sites are only ever handed OF nodes, so use
\nof_device_is_compatible() instead: it walks the property in place and does
\nnot allocate.<\/p>\n","protected":false},"excerpt":{"rendered":"
