kernel-doc: Strip #ifdef/#endif in enums
Some enumerations in the kernel headers use #ifdef to reduce their size based on the the configuration. These lines have to be stripped to avoid parsing problems. For example a simple input like /** * enum flags - test flags * @flag1: first flag * @flag2: second flag */ enum flags { flag1 = BIT(0), #ifdef SECOND_FLAG flag2 = BIT(1), #endif }; resulted in parsing warnings like warning: Enum value '#ifdef SECOND_FLAG;flag2 = BIT(1)' not described in enum 'flags' warning: Enum value '#endif;' not described in enum 'flags' Signed-off-by: Conchúr Navid <conchur@web.de> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
