Subject: [PATCH -next] mm/fs: remove variable bdi set but not used
Date:   Thu,  3 Feb 2022 13:26:33 +0800

The code that uses the pointer 'bdi' has been removed in commit:
'37c32ade079f000c8e539730f254b14fae0d3b49' and inode_to_bdi() doesn't
change 'inode', so the declaration and assignment of 'bdi' can be removed.

Eliminate the following clang warning:
fs/ext2/ialloc.c:173:27: warning: variable 'bdi' set but not used
