[PATCH] fbmem: Correct position of '__maybe_unused' in proc_fb_seq_ops

From: Nathan Chancellor
Date: Wed May 05 2021 - 14:28:37 EST


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.
