From 68f929ff2654bced015ccb9b5555667f46f88dfa Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Thu, 3 Nov 2016 17:12:06 +0000 Subject: [PATCH] debugfs: constify argument to debugfs_real_fops() seq_file users can only access const version of file pointer, because the ->file member of struct seq_operations is marked as such. Make parameter to debugfs_real_fops() const. CC: Greg Kroah-Hartman CC: Nicolai Stange CC: Christian Lamparter CC: LKML Signed-off-by: Jakub Kicinski Signed-off-by: David S.
