* staging: r8712u: Fix leak of skbLarry Finger2016-08-211-1/+0
| | | | | | | | | | | | There are two types of messages queued for RX. The major type, which does I/O on the device, was being handled properly. The skbs that communicated with the firmware were being leaked. While rewriting the code that sets up the skb, it was possible to remove the private variable indicating that the old skb could be reused.

* Staging: rtl8712: Clean up tests if NULL returned on failureBhumika Goyal2016-03-111-1/+1
| | | | | | | | | | | | | | | | | | | | | Some functions like kmalloc/usb_alloc_urb/kmalloc_array returns NULL as their return value on failure. !x is generally preferred over x==NULL or NULL==x so make use of !x if the value returned on failure by these functions is NULL. Done using coccinelle: @@ expression e; statement S; @@ e = \(kmalloc\|devm_kzalloc\|kmalloc_array \|devm_ioremap\|usb_alloc_urb\|alloc_netdev\)(...); - if(e==NULL) + if(!e) S Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

* Staging: rtl8712: Eliminate use of _init_timerVaishali Thakkar2015-03-061-6/+5
| | | | | | | | | | | | | | | | | | | | | This patch introduces the use of API function setup_timer instead of driver specific function _init_timer as it is the preferred and standard way to setup and set the timer. To be compatible with the change, argument types of referenced functions are changed. Also, definition of function _init_timer is removed as it is no longer needed after this change. This is done using Coccinelle and semantic patch used for this is as follows: @@ expression x, y; identifier a, b;@@ - _init_timer (&x, y, a, b); + setup_timer (&x, a, (unsigned long)b); Signed-off-by: Vaishali Thakkar <vthakkar1994@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

* staging: r8712u: Merging Realtek's latest (v2.6.6). Updated include directives.Ali Bahar2011-09-061-0/+4
| | | | | | | | | | | | These are the new include directives for header files. The following were (somehow!) not explicity in Realtek's, but proved necessary: "linux/usb.h" is needed for usb_alloc_urb(); "linux/interrupt.h" is needed for tasklet_struct. It was often a nested include. Signed-off-by: Ali Bahar <ali@internetDog.org> Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* staging: r8712u: Add the new driver to the mainline kernelLarry Finger2010-08-201-0/+169
This code is for a completely new version of the Realtek 8192 USB devices such as the D-Link DWA-130. The Realtek code, which was originally for Linux, Windows XP and Windows CE, has been stripped of all code not needed for Linux. In addition, only one additional configuration variable, which enables AP mode, remains.
