Subject: V4L/DVB (6430): Convert tuner-xc2028 driver to the newer hybrid approach
X-Git-Tag: v2.6.25-rc1~1235^2~480
X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=215b95baf969c6f895969f0a4ae0479954fba7cd;p=pandora-kernel.git

V4L/DVB (6430): Convert tuner-xc2028 driver to the newer hybrid approach

This changeset converts tuner-xc2028 to the newer hybrid approach. It also
prevents creating twice the xc3028 private struct by both DVB and V4L parts.
