The Coverity checker spotted the following incorrect part of
commit 94bebf4d1b8e7719f0f3944c037a21cfd99a4af7:
<-- snip -->
...
void sysfs_drop_dentry(struct sysfs_dirent * sd, struct dentry * parent)
{
struct dentry * dentry = sd->s_dentry;
+ struct inode *inode;
if (dentry) {
spin_lock(&dcache_lock);
spin_lock(&dentry->d_lock);
if (!(d_unhashed(dentry) && dentry->d_inode)) {
+ inode = dentry->d_inode;
+ spin_lock(&inode->i_lock);
...
<-- snip -->
If (!dentry->d_inode), then it's a NULL dereference.

"Only a promise," Lao Er said.
