Add a description for 'irq_create_of_mapping()' and make explicit the fact that the resources allocated by this function can be freed by calling 'irq_dispose_mapping()' when needed (i.e. error handling path, remove function, ...) Signed-off-by: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx> --- The wording can certainly be improved. My goal is only to make clear if patches such as: https://lore.kernel.org/lkml/20201214202117.146293-1-christophe.jaillet@xxxxxxxxxx/ are needed or not. v2: Fix typo and improve style --- kernel/irq/irqdomain.c | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/kernel/irq/irqdomain.c b/kernel/irq/irqdomain.c index 6aacd342cd14..d761ece8d43e 100644 --- a/kernel/irq/irqdomain.c +++ b/kernel/irq/irqdomain.c @@ -858,6 +858,15 @@ unsigned int irq_create_fwspec_mapping(struct irq_fwspec *fwspec) } EXPORT_SYMBOL_GPL(irq_create_fwspec_mapping); +/** + * irq_create_of_mapping() - Map an interrupt + * @irq_data: Structure of_phandle_args returned by a previous + * of_irq_parse_xxx() call. + * + * The resources allocated by this function should be freed by + * calling irq_dispose_mapping() when the mapping is not useful + * anymore. + */ unsigned int irq_create_of_mapping(struct of_phandle_args *irq_data) { struct irq_fwspec fwspec; -- 2.27.0
