From e08bb6f79fa0b9bf94ea44a306d1528172d788af Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Sat, 22 Aug 2015 07:37:28 -0300 Subject: [media] DocBook: add dvb_math.h to documentation There are already some comments at dvb_math.h that are ready for DocBook, although not properly formatted. Convert them, fix some issues and add this file to the device-drivers DocBook.
