There are several issues on the return value for ioctls: - Text is confusing; - Some error codes don't exist; - The non-generic error codes should come before the text that points to the generic error codes; - Tables don't contain column size hints; - Some references are not marked as such. Correct them. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
