kernel-doc: Fix parsing of DECLARE_BITMAP in struct
Some documented structures in the kernel use DECLARE_BITMAP to create arrays of unsigned longs to store information using the bitmap functions. These have to be replaced with a parsable version for kernel-doc. For example a simple input like /** * struct something - some test * @members: active members */ struct something { DECLARE_BITMAP(members, MAX_MEMBERS); }; resulted in parsing warnings like warning: No description found for parameter 'MAX_MEMBERS)' warning: Excess struct/union/enum/typedef member 'members' description in 'something' Signed-off-by: Conchúr Navid <conchur@web.de> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
