Subject: Make struct am7xxx_header and related types private
X-Git-Tag: v0.1.0~10
X-Git-Url: https://git.ao2.it/libam7xxx.git/commitdiff_plain/120b63ecba74a2c3e31b0c8ff3e22696488cd522?ds=sidebyside;hp=-c

Make struct am7xxx_header and related types private

There is not need for struct am7xxx_header, am7xxx_packet_type, and the
other headers structs to be in the public am7xxx.h file.
