[PATCH] fs: debugfs: add forward declaration for struct device type

From: Arend van Spriel
Date: Sun Nov 30 2014 - 10:31:29 EST


The function debugfs_create_devm_seqfile() has a parameter of type
struct device pointer. This type needs to be forward declared to
avoid compilation issues on certain architectures and/or kernel
configurations. The function was introduced with:

commit 98210b7f73f1db182bd9a558a031093cd166e907
