+Subject: [PATCH] video: add v4l2_fh compat for pre-6.18 kernels
+
+Linux v6.18 added file_to_v4l2_fh() and changed v4l2_fh_add() and
+v4l2_fh_del() to take the file pointer so the helpers can manage
+file->private_data internally.
+
+The relevant upstream commits are:
+  618882c92681 ("media: Wrap file->private_data access with a helper function")
+  47f4b1acb4d5 ("media: Set file->private_data in v4l2_fh_add()")
+  277966749f46 ("media: Reset file->private_data to NULL in v4l2_fh_del()")
+
+Add a small compatibility layer for older kernels that keeps
+file->private_data management in this driver.
+
+Upstream-Status: Inappropriate
