This is similar to the Terratec H7. It works with the same az6007 firmware as the former, however the drx-k firmware of the H7 will NOT work. Hence use a different firmware name. The firmware does not need to exist as the one in the eeprom is just fine as long as the h7 one doesn't get loaded, but maybe some day someone wants to load it (the one from the h5 would work too). Also since the config entry is now different anyway disable support for rc. AFAIK the Technisat remote (TS35) is RC5 and the code (which a code comment claims doesn't work anyway) only would handle NEC hence it's pointless creating a device and polling it if we already know it can't work. CI is untested. Originally based on idea found on http://www.linuxtv.org/wiki/index.php/TechniSat_CableStar_Combo_HD_CI claiming only id needs to be added (but failed to mention it only worked because the driver couldn't find the h7 drx-k firmware...).

Add suport for Nokia N900 radio. This driver is far from being ready to be added at the main tree, as it creates its own sysfs interface, and violates lots of Coding Style rules, doing even evil things like returning from a function inside a macro. So, it is being added at staging with the condition that it will be soon be fixed. [m.chehab@samsung.com: added a description for the patch] Signed-off-by:

This define is only used in s5pcsis_irq_handler(): if ((status & S5PCSIS_INTSRC_NON_IMAGE_DATA) && pktbuf->data) { The problem is that "status" is a 32 bit and (0xff << 28) is larger than 32 bits and that sets off a static checker warning.

This patch adds ioctl helpers to the V4L2 mem-to-mem API, so we can avoid several ioctl handlers in the mem-to-mem video node drivers that are simply a pass-through to the v4l2_m2m_* calls. These helpers will only be useful for drivers that use same mutex for both OUTPUT and CAPTURE queue, which is the case for all currently in tree v4l2 m2m drivers. In order to use the helpers the drivers are required to use struct v4l2_fh. Signed-off-by:
