scripts: kernel-doc: proper handle @foo->bar()
The pattern @foo->bar() is valid, as it can be used by a function pointer inside a struct passed as a parameter. Right now, it causes a warning: ./drivers/firewire/core-transaction.c:606: WARNING: Inline strong start-string without end-string. In this specific case, the kernel-doc markup is: /** * fw_core_remove_address_handler() - unregister an address handler * @handler: callback * * To be called in process context. * * When fw_core_remove_address_handler() returns, @handler->callback() is * guaranteed to not run on any CPU anymore. */ With seems valid on my eyes. So, instead of trying to hack the kernel-doc markup, let's teach it about how to handle such things. This should likely remove lots of other similar warnings as well.
