HID: drivers/hid/hid-roccat.c: eliminate a null pointer dereference

2011-11-01T14:13:08+00:00

It is not possible to take the lock in device if device is NULL.
The mutex_lock is thus moved after the NULL test.  New error handling
labels are added at the end to differentiate between the cases where
different sets of locks should be unlocks, and between whether or not
reader should be freed (only on error).

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// 
@r@
expression E, E1;
identifier f;
statement S1,S2,S3;
@@

if (E == NULL)
{
  ... when != if (E == NULL || ...) S1 else S2
      when != E = E1
*E->f
  ... when any
  return ...;
}
else S3
//

hid: Add module.h to fix up implicit users of it

2011-10-31T23:31:17+00:00

A pending cleanup will mean that module.h won't be implicitly
everywhere anymore.  Make sure the modular drivers in clocksource
are actually calling out for  explicitly in advance.

HID: roccat: Fix bug that prevented roccat chardev from removing devices

2011-02-03T15:37:28+00:00

pointer to device was cleared too early. This is fixed now.

HID: roccat: Add ioctl command to retreive report size from chardev

2011-02-03T15:37:28+00:00

Roccat chardev was reworked to support only a defined report size per
device and this can be retreived by an ioctl now to enable future changes
in report definitions.
Header was moved/renamed from drivers/hid to include/linux for accessibility.

HID: roccat: use class for char device for sysfs attribute creation

2011-01-08T00:11:00+00:00

Adding sysfs attributes to an already created device raises no userland
notification. Now the device drivers associate the devices attributes
with a class and use this for roccat event char device creation.

HID: Add and use hid_: dev_ equivalents

2010-12-10T14:10:38+00:00

Neaten current uses of dev_ by adding and using
hid specific hid_ macros.

Convert existing uses of dev_ uses to hid_.
Convert hid-pidff printk uses to hid_.

Remove err_hid and use hid_err instead.

Add missing newlines to logging messages where necessary.
Coalesce format strings.

Add and use pr_fmt(fmt) KBUILD_MODNAME ": " fmt

Other miscellaneous changes:

Add const struct hid_device * argument to hid-core functions
extract() and implement() so hid_ can be used by them.
Fix bad indentation in hid-core hid_input_field function
that calls extract() function above.

HID: add hid_hw_open/close/power() handlers

2010-12-08T13:35:14+00:00

Instead of exposing the guts of hid->ll_driver relationship to HID
sub-drivers provide these helpers to encapsulate the details.
