Clang warns:

 drivers/video/fbdev/core/fbmem.c:736:21: warning: attribute
 declaration must precede definition [-Wignored-attributes]
 static const struct __maybe_unused seq_operations proc_fb_seq_ops = {
                     ^
 ./include/linux/compiler_attributes.h:273:56: note: expanded from macro
 '__maybe_unused'
 #define __maybe_unused                  __attribute__((__unused__))
                                                        ^
 ./include/linux/seq_file.h:31:8: note: previous definition is here
 struct seq_operations {
        ^
 1 warning generated.

The attribute should not split the type 'struct seq_operations'. Move it
before the struct keyword so that it works properly and there is no more
warning.
