| |
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@wanadoo.fr> --- 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@wanadoo.fr/ are needed or not. --- kernel/irq/irqdomain.c | 9 +++++++++ 1 file changed, 9 insertions(+)
