watchdog: orion_wdt: Propagate errors from optional IRQ lookup

2026-08-10T16:00:05+00:00

platform_get_irq_optional() returns a positive IRQ number on success or a negative error code on failure. For an optional IRQ, -ENXIO indicates that no IRQ is available, while other errors should be propagated. Propagate errors such as -EPROBE_DEFER and -EINVAL instead of continuing probe without the IRQ.

platform_get_irq_optional() returns a positive IRQ number on success or a negative error code on failure. For an optional IRQ, -ENXIO indicates that no IRQ is available, while other errors should be propagated. Instead of only checking for -EPROBE_DEFER, propagate all error codes returned by platform_get_irq_optional() other than -ENXIO, so that failures are properly reported to the caller.

watchdog: apple: Constify some structures

2026-08-10T16:00:05+00:00

'struct watchdog_ops' and 'struct watchdog_info' are not modified in this driver. Constifying these structure moves some data to a read-only section, so increases overall security, especially when the structure holds some function pointers.
