Hi there! While having a look at the allocation of struct dvb_frontend in *_attach functions, I found some cases calling memset after kzalloc. This is redundant, and the attached patch removes these calls. I also changed one case calling kmalloc and memset to kzalloc. Regards Matthias Signed-off-by:

At least 3 Vimicro cameras (0x332d, 0x3410 and 0x3420) fail to return correct bandwidth information. The first model rounds the value provided by the host to the nearest supported packet size, while the other two always request the maximum bandwidth. Introduce a device quirk to override the value returned by the device with an estimated bandwidth computed by the driver from the frame size and frame rate, and enable it for all Vimicro cameras.

This patch adds functions to access the scratchpad. For it is this good for? In the first two bytes, the developers stored the HW/PCB version and the software release of the firmware. This is now written to syslog, so debugging get's easier. Also knowing the versions is the key for flash upgrades later on. There are also some cleanups of the flash report sizes. Altogether this should justify the new version number 1.0.9. Thanks to Rick Bronson <rick@efn.org> Signed-off-by:

The bttv driver had static array of structures for up to 16 possible bttv devices, even though few users have more than one or two. The structures were quite large and this resulted in a huge BSS segment. Change the driver to allocate the bttv device data dynamically, which changes "struct bttv bttvs[BTTV_MAX]" to "struct bttv *bttvs[BTTV_MAX]". It would be nice to get ride of "bttvs" entirely but there are some complications with gpio access from the audio & mpeg drivers. To help bttvs removal along anyway, I changed the open() methods use the video device's drvdata to get the driver data instead of looking it up in the bttvs array. This is also more efficient. Some WARN_ON()s are added in cases the device node exists by the bttv device doesn't, which I don't think should be possible. The gpio access functions need to check if bttvs[card] is NULL now. Though calling them on a non-existent card in the first place is wrong, but hard to solve given the fundamental problems in how the gpio access code works. This patch reduces the bss size by 66560 bytes on ia32. Overall change is a reduction of 66398 bytes, as the WARN_ON()s add some 198 bytes. Signed-off-by:

Over half of the card database was used to store muxsel data. 64 bytes were used to store one 32 bit word for each of up to 16 inputs. The Bt8x8 only has two bits to control its mux, so muxsel data for 16 inputs will fit into a single 32 bit word. There were a couple cards that had special muxsel data that didn't fit in two bits, but I cleaned them up in earlier patches. Unfortunately, C doesn't allow us to have an array of bit fields. This makes initializing the structure more of a pain. But with some cpp magic, we can do it by changing: .muxsel = { 2, 3, 0, 1 }, .muxsel = { 2, 2, 2, 2, 3, 3, 3, 3, 1, 1 }, Into: .muxsel = MUXSEL(2, 3, 0, 1), .muxsel = MUXSEL(2, 2, 2, 2, 3, 3, 3, 3, 1, 1), That's not so bad. MUXSEL is a fancy macro that packs the arguments (of which there can be one to sixteen!) into a single word two bits at a time. It's a compile time constant (a variadic function wouldn't be) so we can use it to initialize the structure. It's important the the arguments to the macro only be plain decimal integers. Stuff like "0x01", "(2)", or "MUX3" won't work properly. I also created an accessor function, bttv_muxsel(btv, input), that gets the mux bits for the selected input. It makes it cleaner to change the way the muxsel data is stored. This patch doesn't change the code size and decreases the datasegment by 9440 bytes. Signed-off-by: -

This card apparently uses an external mux and the Bt878's mux should always be set to MUX2. The values for the external mux control bits were stored in the muxsel field. This meant that when changing inputs the driver would switch the Bt878's mux to whatever value the external mux was supposed to be set to, then eagle_muxsel() would switch it back to MUX2 and program the external mux. This creates an unnecessary switch of the Bt878's mux. So change muxsel to be 2 for each input. The external mux bits are just "input&3" so they don't really need to be stored anywhere. This also eliminates the last non-standard use of the muxsel data. Cc: M G Berberich <berberic@fmi.uni-passau.de> Signed-off-by:
