From 234e340582901211f40d8c732afc49f0630ecf05 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Thu, 5 Apr 2012 14:25:11 -0700 Subject: simple_open: automatically convert to simple_open() Many users of debugfs copy the implementation of default_open() when they want to support a custom read/write function op. This leads to a proliferation of the default_open() implementation across the entire tree. Now that the common implementation has been consolidated into libfs we can replace all the users of this function with simple_open(). This replacement was done with the following semantic patch: @ open @ identifier open_f != simple_open; identifier i, f; @@ -int open_f(struct inode *i, struct file *f) -{ ( -if (i->i_private) -f->private_data = i->i_private; | -f->private_data = i->i_private; ) -return 0; -} @ has_open depends on open @ identifier fops; identifier open.open_f; @@ struct file_operations fops = { ... -.open = open_f, +.open = simple_open, ... }; [akpm@linux-foundation.org: checkpatch fixes] Signed-off-by: Stephen Boyd Cc: Greg Kroah-Hartman Cc: Al Viro Cc: Julia Lawall Acked-by: Ingo Molnar Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- drivers/uwb/uwb-debug.c | 9 +-------- 1 file changed, 1 insertion(+), 8 deletions(-) (limited to 'drivers/uwb') diff --git a/drivers/uwb/uwb-debug.c b/drivers/uwb/uwb-debug.c index 2eecec0c13c9..6ec45beb7af5 100644 --- a/drivers/uwb/uwb-debug.c +++ b/drivers/uwb/uwb-debug.c @@ -159,13 +159,6 @@ static int cmd_ie_rm(struct uwb_rc *rc, struct uwb_dbg_cmd_ie *ie_to_rm) return uwb_rc_ie_rm(rc, ie_to_rm->data[0]); } -static int command_open(struct inode *inode, struct file *file) -{ - file->private_data = inode->i_private; - - return 0; -} - static ssize_t command_write(struct file *file, const char __user *buf, size_t len, loff_t *off) { @@ -206,7 +199,7 @@ static ssize_t command_write(struct file *file, const char __user *buf, } static const struct file_operations command_fops = { - .open = command_open, + .open = simple_open, .write = command_write, .read = NULL, .llseek = no_llseek, -- cgit v1.2.3
