[PATCH 2/4] debugfs: Add read-only/write-only x64 file ops

2015-10-12 Thread Stephen Boyd
There aren't any read-only or write-only x64 file ops, but there is a caller of debugfs_create_x64() that calls it with mode equal to S_IRUGO. This leads to the possibility of userspace modifying the file, so let's use the newly created debugfs_create_mode() helper here to fix this. Signed-off-by:
