5.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jinjie Ruan <ruanjinjie@xxxxxxxxxx>
[ Upstream commit d0b0822e32dbae80bbcb3cc86f34d28539d913df ]
Since both debugfs_create_dir() and debugfs_create_file() return ERR_PTR
and never NULL, use IS_ERR() instead of checking for NULL.
Fixes: 1e98fb0f9208 ("scsi: qla2xxx: Setup debugfs entries for remote ports")
