sh: intc: Fix use-after-free bug in register_intc_controller()

2024-12-09T09:33:00+00:00

[ Upstream commit 63e72e551942642c48456a4134975136cdcb9b3c ] In the error handling for this function, d is freed without ever removing it from intc_list which would lead to a use after free. To fix this, let's only add it to the list after everything has succeeded.

sh: intc: move to use bus_get_dev_root()

2023-03-17T14:29:55+00:00

Direct access to the struct bus_type dev_root pointer is going away soon so replace that with a call to bus_get_dev_root() instead, which is what it is there for.

genirq: Add and use an irq_data_update_affinity helper

2022-07-07T08:38:04+00:00

Some architectures and irqchip drivers modify the cpumask returned by irq_data_get_affinity_mask, usually by copying in to it. This is problematic for uniprocessor configurations, where the affinity mask should be constant, as it is known at compile time. Add and use a setter for the affinity mask, following the pattern of irq_data_update_effective_affinity. This allows the getter function to return a const cpumask pointer.

sh: intc: Drop the use of irq_create_identity_mapping()

2021-04-07T11:12:52+00:00

Instead of playing games with using irq_create_identity_mapping() and irq_domain_associate(), drop the use of the former and only use the latter, together with the allocation of the irq_desc as needed. It doesn't make the code less awful, but at least the intent is clearer. Tested-by: Geert Uytterhoeven Signed-off-by: Marc Zyngier

As said in commit f2c2cbcc35d4 ("powerpc: Use pr_warn instead of pr_warning"), removing pr_warning so all logging messages use a consistent _warn style. Let's do it.
