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 --- sound/soc/soc-dapm.c | 16 ++-------------- 1 file changed, 2 insertions(+), 14 deletions(-) (limited to 'sound/soc/soc-dapm.c') diff --git a/sound/soc/soc-dapm.c b/sound/soc/soc-dapm.c index 6241490fff3..5cbd2d7623b 100644 --- a/sound/soc/soc-dapm.c +++ b/sound/soc/soc-dapm.c @@ -1544,12 +1544,6 @@ static int dapm_power_widgets(struct snd_soc_dapm_context *dapm, int event) } #ifdef CONFIG_DEBUG_FS -static int dapm_widget_power_open_file(struct inode *inode, struct file *file) -{ - file->private_data = inode->i_private; - return 0; -} - static ssize_t dapm_widget_power_read_file(struct file *file, char __user *user_buf, size_t count, loff_t *ppos) @@ -1613,17 +1607,11 @@ static ssize_t dapm_widget_power_read_file(struct file *file, } static const struct file_operations dapm_widget_power_fops = { - .open = dapm_widget_power_open_file, + .open = simple_open, .read = dapm_widget_power_read_file, .llseek = default_llseek, }; -static int dapm_bias_open_file(struct inode *inode, struct file *file) -{ - file->private_data = inode->i_private; - return 0; -} - static ssize_t dapm_bias_read_file(struct file *file, char __user *user_buf, size_t count, loff_t *ppos) { @@ -1654,7 +1642,7 @@ static ssize_t dapm_bias_read_file(struct file *file, char __user *user_buf, } static const struct file_operations dapm_bias_fops = { - .open = dapm_bias_open_file, + .open = simple_open, .read = dapm_bias_read_file, .llseek = default_llseek, }; -- cgit v1.2.3
