From 83c3fee7e78f5a937b734f1ba954c5cdcb2be755 Mon Sep 17 00:00:00 2001 From: Daniel Axtens Date: Fri, 7 Aug 2015 13:18:20 +1000 Subject: [PATCH] cxl: sparse: Silence iomem warning in debugfs file creation An IO address, tagged with __iomem, is passed to debugfs_create_file as private data. This requires that it be cast to void *. The cast drops the __iomem annotation and so creates a sparse warning: drivers/misc/cxl/debugfs.c:51:57: warning: cast removes address space of expression The address space marker is added back in the file operations (fops_io_u64). Silence the warning with __force.
