uwb: init beacon cache entry before registering uwb device

2014-12-01T10:02:28+00:00

commit 675f0ab2fe5a0f7325208e60b617a5f32b86d72c upstream.

Make sure the uwb_dev->bce entry is set before calling uwb_dev_add in
uwbd_dev_onair so that usermode will only see the device after it is
properly initialized.  This fixes a kernel panic that can occur if
usermode tries to access the IEs sysfs attribute of a UWB device before
the driver has had a chance to set the beacon cache entry.

Fatal errors such as a device disconnect must not trigger
error handling. The error returns must be checked.

uwb: fix use of del_timer_sync() in interrupt

2012-04-18T20:15:51+00:00

del_timer_sync() cannot be used in interrupt.
Replace it with del_timer() and a flag

simple_open: automatically convert to simple_open()

2012-04-05T22:25:50+00:00

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,
...
};

uwb: Use kcalloc instead of kzalloc to allocate array

2011-12-10T00:18:20+00:00

The advantage of kcalloc is, that will prevent integer overflows which could
result from the multiplication of number of elements and size and it is also
a bit nicer to read.

USB: convert some miscellanies drivers to use module_usb_driver()

2011-11-18T17:52:10+00:00

This converts the remaining USB drivers in the kernel to use the
module_usb_driver() macro which makes the code smaller and a bit
simpler.

Added bonus is that it removes some unneeded kernel log messages about
drivers loading and/or unloading.
