Subject: [media] DocBook: add dvb_math.h to documentation
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e08bb6f79fa0b9bf94ea44a306d1528172d788af;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[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.
