Linus Torvalds 3e423945ea devpts: return NULL pts 'priv' entry for non-devpts nodes In commit `8ead9dd547` ("devpts: more pty driver interface cleanups") I made devpts_get_priv() just return the dentry->fs_data directly. And because I thought it wouldn't happen, I added a warning if you ever saw a pts node that wasn't on devpts. And no, that warning never triggered under any actual real use, but you can trigger it by creating nonsensical pts nodes by hand. So just revert the warning, and make devpts_get_priv() return NULL for that case like it used to.

Linus Torvalds 3e423945ea devpts: return NULL pts 'priv' entry for non-devpts nodes

In commit 8ead9dd547 ("devpts: more pty driver interface cleanups") I
made devpts_get_priv() just return the dentry->fs_data directly.  And
because I thought it wouldn't happen, I added a warning if you ever saw
a pts node that wasn't on devpts.

And no, that warning never triggered under any actual real use, but you
can trigger it by creating nonsensical pts nodes by hand.

So just revert the warning, and make devpts_get_priv() return NULL for
that case like it used to.
