doc-rst: kernel-doc: fix handling of address_space tags
The RST cpp:function handler is very pedantic: it doesn't allow any macros like __user on it: Documentation/media/kapi/dtv-core.rst:28: WARNING: Error when parsing function declaration. If the function has no return type: Error in declarator or parameters and qualifiers Invalid definition: Expecting "(" in parameters_and_qualifiers. [error at 8] ssize_t dvb_ringbuffer_pkt_read_user (struct dvb_ringbuffer * rbuf, size_t idx, int offset, u8 __user * buf, size_t len) --------^ If the function has a return type: Error in declarator or parameters and qualifiers If pointer to member declarator: Invalid definition: Expected '::' in pointer to member (function). [error at 37] ssize_t dvb_ringbuffer_pkt_read_user (struct dvb_ringbuffer * rbuf, size_t idx, int offset, u8 __user * buf, size_t len) -------------------------------------^ If declarator-id: Invalid definition: Expecting "," or ")" in parameters_and_qualifiers, got "*". [error at 102] ssize_t dvb_ringbuffer_pkt_read_user (struct dvb_ringbuffer * rbuf, size_t idx, int offset, u8 __user * buf, size_t len) ------------------------------------------------------------------------------------------------------^ So, we have to remove it from the function prototype.
