Do we need to split the line after the __printf()? Can't the above be:

static inline __printf(2, 0) void
trace_seq_bprintf(struct trace_seq *s, const char *fmt, const u32 *binary)

Or even:

__printf(2, 0)
static inline void
trace_seq_bprintf(struct trace_seq *s, const char *fmt, const u32 *binary)

I rather not split the prefix elements of a function over two lines. I
rather not even split them from the function itself, but tend to do that if
space is needed.
