* tty: move obsolete and broken tty drivers to drivers/staging/tty/Greg Kroah-Hartman2011-02-231-4507/+0
| | | | | | | | | | | | | | | | | | | As planned by Arnd Bergmann, this moves the following drivers to the drivers/staging/tty/ directory where they will be removed after 2.6.41 if no one steps up to claim them. epca epca ip2 istallion riscom8 serial167 specialix stallion Cc: Arnd Bergmann <arnd@arndb.de> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Cc: Jiri Slaby <jslaby@suse.cz> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* tty: now phase out the ioctl file pointer for goodAlan Cox2011-02-171-2/+2

* tiocmget: kill off the passing of the struct fileAlan Cox2011-02-171-1/+1
| | | | | | | | | | We don't actually need this and it causes problems for internal use of this functionality. Currently there is a single use of the FILE * pointer. That is the serial core which uses it to check tty_hung_up_p. However if that is true then IO_ERROR is also already set so the check may be removed.

* llseek: automatically add .llseek fopArnd Bergmann2010-10-151-0/+1

The three cases that we can automatically detect are no_llseek, seq_lseek and default_llseek. For cases where we can we can automatically prove that the file offset is always ignored, we use noop_llseek, which maintains the current behavior of not returning an error from a seek. New drivers should normally not use noop_llseek but instead use no_llseek and call nonseekable_open at open time. Existing drivers can be converted to do the same when the maintainer knows for certain that no user code relies on calling seek on the device file. The generated code is often incorrectly indented and right now contains comments that clarify for each added line why a specific variant was chosen. In the version that gets submitted upstream, the comments will be gone and I will manually fix the indentation, because there does not seem to be a way to do that using coccinelle. Some amount of new code is currently sitting in linux-next that should get the same modifications, which I will do at the end of the merge window. Many thanks to Julia Lawall for helping me learn to write a semantic patch that does all this. ===== begin semantic patch ===== // This adds an llseek= method to all file operations, // as a preparation for making no_llseek the default. // // The rules are // - use no_llseek explicitly if we do nonseekable_open // - use seq_lseek for sequential files // - use default_llseek if we know we access f_pos // - use noop_llseek if we know we don't access f_pos, // but we still want to allow users to call lseek // @ open1 exists @ identifier nested_open; @@ nested_open(...) { <+... nonseekable_open(...) ...+> } @ open exists@ identifier open_f; identifier i, f; identifier open1.nested_open; @@ int open_f(struct inode *i, struct file *f) { <+...

| | | | | | | | | | Only ISA cards should be freed in module exit. Pci probed are freed in pci_remove. Define a flag, where we store this info a what to check against.

| | | | | | | | | | | | | | - remove unneeded license text - remove functions, that are implemented in kernel -- call them (strtoul, min, tolower) - do not cast NULL - there is no static table, throw away code, which takes care of it -- find module param cards in that place instead.
