Was this patch ever posted to the linux-dvb mailing list? There are some
(minor) concerns that I have with this changeset. Please see my comments inline
below:
Patch from Marco Gittler wrote:
The patch number 5532 was added via Mauro Carvalho Chehab <mchehab@xxxxxxxxxxxxx>
to http://linuxtv.org/hg/v4l-dvb master development tree.
Kernel patches at this development tree might be modified to keep backward
compatibility with older kernels. Those compatibility stuff will be removed
during preparation to be included at kernel mainstream.
If anyone has any objections, please let us know by sending a message to:
