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/net/wireless/iwmc3200wifi/debugfs.c | 14 ++++---------- drivers/net/wireless/iwmc3200wifi/sdio.c | 9 +-------- 2 files changed, 5 insertions(+), 18 deletions(-) (limited to 'drivers/net/wireless/iwmc3200wifi') diff --git a/drivers/net/wireless/iwmc3200wifi/debugfs.c b/drivers/net/wireless/iwmc3200wifi/debugfs.c index 87eef57..b6199d1 100644 --- a/drivers/net/wireless/iwmc3200wifi/debugfs.c +++ b/drivers/net/wireless/iwmc3200wifi/debugfs.c @@ -99,12 +99,6 @@ DEFINE_SIMPLE_ATTRIBUTE(fops_iwm_dbg_modules, iwm_debugfs_u32_read, iwm_debugfs_dbg_modules_write, "%llu\n"); -static int iwm_generic_open(struct inode *inode, struct file *filp) -{ - filp->private_data = inode->i_private; - return 0; -} - static ssize_t iwm_debugfs_txq_read(struct file *filp, char __user *buffer, size_t count, loff_t *ppos) @@ -401,28 +395,28 @@ out: static const struct file_operations iwm_debugfs_txq_fops = { .owner = THIS_MODULE, - .open = iwm_generic_open, + .open = simple_open, .read = iwm_debugfs_txq_read, .llseek = default_llseek, }; static const struct file_operations iwm_debugfs_tx_credit_fops = { .owner = THIS_MODULE, - .open = iwm_generic_open, + .open = simple_open, .read = iwm_debugfs_tx_credit_read, .llseek = default_llseek, }; static const struct file_operations iwm_debugfs_rx_ticket_fops = { .owner = THIS_MODULE, - .open = iwm_generic_open, + .open = simple_open, .read = iwm_debugfs_rx_ticket_read, .llseek = default_llseek, }; static const struct file_operations iwm_debugfs_fw_err_fops = { .owner = THIS_MODULE, - .open = iwm_generic_open, + .open = simple_open, .read = iwm_debugfs_fw_err_read, .llseek = default_llseek, }; diff --git a/drivers/net/wireless/iwmc3200wifi/sdio.c b/drivers/net/wireless/iwmc3200wifi/sdio.c index 764b40d..0042f20 100644 --- a/drivers/net/wireless/iwmc3200wifi/sdio.c +++ b/drivers/net/wireless/iwmc3200wifi/sdio.c @@ -264,13 +264,6 @@ static int if_sdio_send_chunk(struct iwm_priv *iwm, u8 *buf, int count) return ret; } -/* debugfs hooks */ -static int iwm_debugfs_sdio_open(struct inode *inode, struct file *filp) -{ - filp->private_data = inode->i_private; - return 0; -} - static ssize_t iwm_debugfs_sdio_read(struct file *filp, char __user *buffer, size_t count, loff_t *ppos) { @@ -363,7 +356,7 @@ err: static const struct file_operations iwm_debugfs_sdio_fops = { .owner = THIS_MODULE, - .open = iwm_debugfs_sdio_open, + .open = simple_open, .read = iwm_debugfs_sdio_read, .llseek = default_llseek, }; -- cgit v1.1
