2007-10-13v4l: copy_to_user() is not a good method nameAl Viro
Breaks on any target that has copy_to_user() defined as a non-trivial macro. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-10-10V4L/DVB (6292): videobuf_core init always require callback implementationMauro Carvalho Chehab
In the past, videobuf_queue_init were used to initialize PCI DMA videobuffers. This patch renames it, to avoid confusion with the previous kernel API, doing: s/videobuf_queue_init/void videobuf_queue_core_init/ Also, the operations is now part of the function parameter. The function will also add a test if this is defined, otherwise producing BUG. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2007-10-09V4L/DVB (6254): Add videobuf-vmallocMauro Carvalho Chehab
Adds a newer videobuf-vmalloc module. This module uses the same videobuf controls, but implements memory allocation based on vmalloc methods. With this method, an USB driver can use video-buf, without needing to request memory from the DMA-safe area. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
