5.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jinjie Ruan <ruanjinjie@xxxxxxxxxx>
[ Upstream commit 7dcc683db3639eadd11bf0d59a09088a43de5e22 ]
Since debugfs_create_file() returns ERR_PTR and never NULL, use IS_ERR() to
check the return value.
Fixes: 2fcbc569b9f5 ("scsi: lpfc: Make debugfs ktime stats generic for NVME and SCSI")
Fixes: 4c47efc140fa ("scsi: lpfc: Move SCSI and NVME Stats to hardware queue structures")
Fixes: 6a828b0f6192 ("scsi: lpfc: Support non-uniform allocation of MSIX vectors to hardware queues")
Fixes: 95bfc6d8ad86 ("scsi: lpfc: Make FW logging dynamically configurable")
Fixes: 9f77870870d8 ("scsi: lpfc: Add debugfs support for cm framework buffers")
Fixes: c490850a0947 ("scsi: lpfc: Adapt partitioned XRI lists to efficient sharing")
