These headers follow the pattern:

| #if CONFIG_IS_ENABLED(FANCY_FEATURE) | void foo(void); | #else | static inline void foo(void) { return -ENOSYS; } | #endif

In the #else path ENOSYS is used, however linux/errno.h is not included. If errno.h has not been included already the compiler errors out even if the inline function is not referenced.

Make those headers self contained.
