[PATCH] Generic ioctl.h Most arches copied the i386 ioctl.h. Combine them into a generic header. Signed-off-by: Brian Gerst <bgerst@didntduck.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

include/asm-generic/ioctl.h: fix _IOC_TYPECHECK sparse error When running sparse over drivers/media/v4l2-core/v4l2-ioctl.c I get these errors: drivers/media/v4l2-core/v4l2-ioctl.c:2043:9: error: bad integer constant expression drivers/media/v4l2-core/v4l2-ioctl.c:2044:9: error: bad integer constant expression drivers/media/v4l2-core/v4l2-ioctl.c:2045:9: error: bad integer constant expression drivers/media/v4l2-core/v4l2-ioctl.c:2046:9: error: bad integer constant expression etc. The root cause of that turns out to be in include/asm-generic/ioctl.h: #include <uapi/asm-generic/ioctl.h> /* provoke compile error for invalid uses of size argument */ extern unsigned int __invalid_size_argument_for_IOC; #define _IOC_TYPECHECK(t) \ ((sizeof(t) == sizeof(t[1]) && \ sizeof(t) < (1 << _IOC_SIZEBITS)) ? \ sizeof(t) : __invalid_size_argument_for_IOC) If it is defined as this (as is already done if __KERNEL__ is not defined): #define _IOC_TYPECHECK(t) (sizeof(t)) then all is well with the world. This patch allows sparse to work correctly.
