Currently, kernel-doc warns for function prototype parsing on the
presence of additional attributes in the definition.
E.g., running kernel-doc -none on include/rdma/iw_cm.h causes this
warning:
"warning: cannot understand function prototype: 'const char *__attribute_const__ iwcm_reject_msg(int reason); '"
Here, the prototype parsing does not take into account the presence
of attribute, "__attribute_const__" before function name.
Provide a simple fix by adding "__attribute_const__" in the corresponding
regex expression.
A quick evaluation by running 'kernel-doc -none' on kernel-tree reveals
that no additional warning or error has been added or removed by the fix.
