* [media] af9033: fix broken I2CAntti Palosaari2013-12-041-6/+6
| | | | | | | | | | | Driver did not work anymore since I2C has gone broken due to recent commit: commit 37ebaf6891ee81687bb558e8375c0712d8264ed8 [media] dvb-frontends: Don't use dynamic static allocation Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com> Cc: stable@vger.kernel.org

Considering that I2C transfers are generally limited, and that devices used on USB has a max data length of 64 bytes for the control URBs. So, it seem safe to use 64 bytes as the hard limit for all those devices. On most cases, the limit is a way lower than that, but this limit is small enough to not affect the Kernel stack, and it is a no brain limit, as using smaller ones would require to either carefully each driver or to take a look on each datasheet.

| | | | | | | | | | | | | | | | As spotted by Dan Carpenter <dan.carpenter@oracle.com> (thanks!), we have improperly used an unsigned variable in a calculation that may result in a negative number. This may cause an unintended underflow if the interface frequency of the tuner is > approx. 40MHz. This patch should resolve the issue, following an approach similar to what is used in af9013.c.

* [media] Support for Asus MyCinema U3100Mini PlusOliver Schinagl2012-09-271-0/+4
| | | | | | | | | | | | | | This is initial support for the Asus MyCinema U3100Mini Plus. The driver in its current form gets detected and loads properly. Scanning using dvbscan works without problems, Locking onto a channel using tzap also works fine. Only playback using tzap -r + mplayer was tested and was fully functional. It uses the af9035 USB Bridge chip, with an af9033 demodulator. The tuner used is the FCI FC2580.
