2012-04-05simple_open: automatically convert to simple_open()Stephen Boyd
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: <smpl> @ 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, ... }; </smpl> [akpm@linux-foundation.org: checkpatch fixes] Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2011-11-22HID: wiimote: Allow direct DRM debug accessDavid Herrmann
Keep track of current drm and add new debugfs file which reads or writes the current DRM. Signed-off-by: David Herrmann <dh.herrmann@googlemail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2011-11-22HID: wiimote: Allow direct eeprom accessDavid Herrmann
The wiimote provides direct access to parts of its eeprom. This implements read support for small chunks of the eeprom. This isn't very fast but prevents the reader from blocking the wiimote stream for too long. Write support is not yet supported as the wiimote breaks if we overwrite its memory. Use hidraw to reverse-engineer the eeprom before implementing write support here. Signed-off-by: David Herrmann <dh.herrmann@googlemail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2011-11-22HID: wiimote: Add debugfs support stubsDavid Herrmann
Add initializer and deinitializer for debugfs support. This will later allow raw eeprom access and direct DRM modifications to debug wiimote behaviour and further protocol reverse-engineerings. Signed-off-by: David Herrmann <dh.herrmann@googlemail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
