All these are instances of #define NAME value; or #define NAME(params_opt) value; These of course fail to build when used in contexts like if(foo $OP NAME) while(bar $OP NAME) and may silently generate the wrong code in contexts such as foo = NAME + 1; /* foo = value; + 1; */ bar = NAME - 1; /* bar = value; - 1; */ baz = NAME & quux; /* baz = value; & quux; */ Reported on comp.lang.c, Message-ID: <ab0d55fe-25e5-482b-811e-c475aa6065c3@c29g2000yqd.googlegroups.com> Initial analysis of the dangers provided by Keith Thompson in that thread. There are many more instances of more complicated macros having unnecessary trailing semicolons, but this pile seems to be all of the cases of simple values suffering from the problem. (Thus things that are likely to be found in one of the contexts above, more complicated ones aren't.)

Document that odd == top and even == bottom. I can never remember this, so it is probably worth documenting. Signed-off-by: NHans Verkuil <hverkuil@xs4all.nl> Signed-off-by: NMauro Carvalho Chehab <mchehab@redhat.com>

The media spec contains several errors in the description of the I/O streaming ioctls, in particular with respect to the userptr I/O method. The most important change is that you really need to set count and index in v4l2_requestbuffer and v4l2_buffer when dealing with user pointer streaming.
