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'
