strncpy is unsafe as it doesn't append a terminating NUL character when the source string doesn't fit in the destination buffer. Replace it with strlcpy. strncat is misused as its size argument refers to the source string, not the destination buffer. Replace it with strlcat. Signed-off-by:

request_module() needs to be called with a string literal for a format string or with 1 or more variable arguments to avoid compiler warnings and possible exploits, if someone could cause us to get a format string with a '%' code in the format string when we make the call. Reported-by:

A redundant PLL divisior update for the I2S master clock after AV core firmware load was missed in earlier PLL parameter changes. This one really doesn't matter because it's redundant and gets overwritten, but the driver should be self consistent in the values used. Signed-off-by:

Now there is a card, which uses cx24116 to control LNB DC voltage. It is DVBWorld DVBS2 PCI-e 2005. The patch is nedded to add support for that card. 1. Rename CMD_SET_TONEPRE to CMD_LNBDCLEVEL. 2. Fill set_voltage with actually control voltage code. 3. Correct set_tone to not affect voltage. Signed-off-by:

The name of the pvrusb2 module is not likely to ever change, and there are plenty of other places where the name is directly coded, so there is little utility in using a macro to infer the module name here. In addition, using that macro complicates other uses of the driver involving older kernels where this macro works differently. Yes I know for many places we don't have to worry about that. But my alternative is that I have to build special logic in the pvrusb2 standalone driver to special-case what is otherwise costmetic and that is just plain nuts for something as trivial as this, especially since this change does not at all have any compile time or run time impact on the driver. I'm just removing a nicety that didn't have a lot of value here to begin with. Signed-off-by:

It appears that various v4l-dvb drivers are changing to require explicit initialization before use. This change to the pvrusb2 driver implements an automatic issuance of VIDIOC_INT_INIT when a module is bound to the driver, thus conforming to the new behavior. Signed-off-by:

Previous v4l-dvb changeset id 4cc8ed11e2e0 changed the pvrusb2-hdw internal API regarding i2c chip debug register access. However that change failed to also update the corresponding function comment describing the API. As driver maintained I never saw a request for an ack on that change; there probably should have been one especially since the manner in which this API operates was changed - its interface is now entangled with a v4l specific struct and I would have preferred to keep this API clear of moving-target v4l-isms such as this one if at all possible which is why I had done it the way I did before. But whatever. This commit at least fixes the comment issue. Signed-off-by:
