* Staging: Use kcalloc or kzallocJulia Lawall2010-05-141-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use kcalloc or kzalloc rather than the combination of kmalloc and memset. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x,y,flags; statement S; type T; @@ x = - kmalloc + kcalloc ( - y * sizeof(T), + y, sizeof(T), flags); if (x == NULL) S -memset(x, 0, y * sizeof(T)); @@ expression x,size,flags; statement S; @@ -x = kmalloc(size,flags); +x = kzalloc(size,flags); if (x == NULL) S -memset(x, 0, size); // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk>

* staging: make USB device id constantNémeth Márton2010-03-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The id_table field of the struct usb_device_id is constant in <linux/usb.h> so it is worth to make the initialization data also constant. The semantic match that finds this kind of pattern is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ disable decl_init,const_decl_init; identifier I1, I2, x; @@ struct I1 { ... const struct I2 *x; ... }; @s@ identifier r.I1, y; identifier r.x, E; @@ struct I1 y = { .x = E, }; @c@ identifier r.I2; identifier s.E; @@ const struct I2 E[] = ... ; @depends on !c@ identifier r.I2; identifier s.E; @@ + const struct I2 E[] = ...; // </smpl> Signed-off-by: Németh Márton <nm127@freemail.hu> Cc: Julia Lawall <julia@diku.dk> Cc: cocci@diku.dk Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* V4L/DVB (13456): s2250: Change module structurePete Eberlein2009-12-051-1/+1
| | | | | | | | | | | | | | | | The s2250-board i2c module was converted to use v4l2-i2c-drv.h in preparation for its subdev conversion. This change prevented the s2250-loader from being initialized within the same module due to the module_init and module_exit function definitions in v4l2-i2c-drv.h. Therefore, s2250-loader is now its own module, and the header for exporting s2250-loader functions is no longer needed. The s2250 i2c module name was "2220-board" in some places, and was changed to "s2250".

* V4L/DVB (13455): go7007: Add struct v4l2_device.Pete Eberlein2009-12-051-2/+2
| | | | | | | | | | | | | | This adds a struct v4l2_device to the go7007 device struct and registers it during v4l2 initialization. The v4l2_device registration overwrites the go->dev device_data, which is a struct usb_interface with intfdata set to the struct go7007. This changes intfdata to point to the struct v4l2_device inside struct go7007, which is what v4l2_device_register will also set it to (and warn about non-null drvdata on register.) Since usb disconnect can happen any time, this intfdata should always be present.

* go7007: Convert to the new i2c device binding modelJean Delvare2009-04-211-3/+11
| | | | | | | | | | | | Move the go7007 driver away from the legacy i2c binding model, which is going away really soon now. The I2C addresses of the audio and video chips in s2250-board didn't look quite right, apparently they were left-aligned values when Linux wants right-aligned values, so I fixed them too.

* Staging: add the go7007 video driverGreg Kroah-Hartman2008-10-101-0/+1229
Todo: - checkpatch.pl cleanups - sparse cleanups - lots of little modules, should be merged together and added to the build. - testing? - handle churn in v4l layer.
