2013-05-13staging: ozwpan: fix error return code in oz_cdev_register()Wei Yongjun
Fix to return a negative error code from the error handling case instead of 0, as done elsewhere in this function. Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-04-22staging/ozwpan: info leak in oz_cdev_ioctl()Dan Carpenter
If we're not maxed out then oz_get_pd_list() leaves part of the "list" struct uninitialized. We should clear this so that no stack information is leaked to userspace. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-02-15staging/ozwpan: Mark read only parameters and structs as constPeter Huewe
This patch marks function parameters that are used read only as well as readonly structs (and corresponding pointers) as const. Signed-off-by: Peter Huewe <peterhuewe@gmx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-02-15staging/ozwpan: Remove empty and unused function oz_cdev_heartbeatPeter Huewe
oz_cdev_heartbeat is empty and unused -> safe to remove. Signed-off-by: Peter Huewe <peterhuewe@gmx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Should it be static? -> add static keyword to silence the warning and make sparse happy. Signed-off-by: Peter Huewe <peterhuewe@gmx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-02-15staging/ozwpan: Add missing header includesPeter Huewe
ozcdev.c and ozhcd.c should include their own header file, so sparse knows which functions are declared and which not. Signed-off-by: Peter Huewe <peterhuewe@gmx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-02-15staging/ozwpan: Fix NULL vs zero in ozcdev.c (sparse warning)Peter Huewe
This patch fixes the warning "Using plain integer as NULL pointer", generated by sparse, by replacing the offending 0s with NULL. If the initialization with NULL was unnecessary (due to unconditional assignment before first use) it was removed. Signed-off-by: Peter Huewe <peterhuewe@gmx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-09-19staging: ozwpan: compare pointer to NULL rather than 0Fengguang Wu

2012-09-04staging: ozwpan: fix memcmp() test in oz_set_active_pd()Tomas Winkler
"addr" is a pointer so it's either 4 or 8 bytes, but actually we want to compare 6 bytes (ETH_ALEN). As network stack already provides helper function is_zero_ether_addr() we use that instead of memcmp Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Acked-by: Dan Carpenter <dan.carpenter@oracle.com> Acked-by: Rupesh Gujare <rgujare@ozmodevices.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2012-03-03staging: ozwpan: remove debug allocatorGreg Kroah-Hartman
The kernel already has a debug allocator, no need to have one unique to a single driver. So delete it, replace with kfree, kmalloc, and, in a few places that need it, kzalloc(). Cc: Chris Kelly <ckelly@ozmodevices.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-02-24staging: ozwpan: Added character device supportChris Kelly
The character device provides a management interface to the driver and also provides an additional service to the protocol for side band communication with the device. Signed-off-by: Chris Kelly <ckelly@ozmodevices.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
