This changeset adds the OV511 decompression module to 2.5.x and updates the OV511 Config.help.
I've made sure that it builds, but since 2.5.5 doesn't compile for me it isn't tested. It's known to work under other kernels, so please apply it anyway Greg. Thanks, -- Mark McClelland [EMAIL PROTECTED]

I224 17 \ OV511 Decompression support CONFIG_USB_OV511_DEC Say M here if you want to achieve higher frame rates, at the expense of image quality. A 300 MHz or faster CPU is recommended. \ This feature is NOT activated by default. The OV511 driver must have compression enabled (eg. loaded with the "compress=1" module parameter). See <file:Documentation/usb/ov511.txt> for more information. \ This code is also available as a module ( = code which can be inserted in and removed from the running kernel whenever you want). The module will be called ov511_decomp.o. You must load ov511.o before loading this module, and you must unload this module before unloading ov511.o.
