Fix it by using hex notation instead of the non-standard binary one
What defines "non-standard" here ?
non-standard as not part of the C standard. Binary constant notation is
a GCC extension as far as I'm aware:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23479
http://gcc.gnu.org/onlinedocs/gcc/Binary-constants.html (Note the "C
Extensions" section)
Isn't this a sparse problem that
should possibly
be fixed in sparse instead ?
It could be fixed in sparse as well, I don't really mind either way. The
binary notation doesn't seem to be used much, if at all, on the kernel
though; most of the matches I saw when quickly grepping were comments.
Cheers,
Emilio
