2015-05-31staging: rtl8712: fix stack dumpSudip Mukherjee
del_timer_sync() is not to be called in the interrupt context unless the timer is irqsafe. but most of the functions where commits 6501c8e7d86cca5f and 382d020f4459cd77 touched were called in interrupt context. And as a result the WARN_ON was getting triggered. Changed to del_timer() in places which were called from interrupt. Fixes: 382d020f4459cd77 ("Staging: rtl8712: Eliminate use of _cancel_timer" Fixes: 6501c8e7d86cca5f ("Staging: rtl8712: Eliminate use of _cancel_timer_ex") Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=97711 Reported-by: Arek Rusniak <arek.rusi@gmail.com> Tested-by: Arek Rusniak <arek.rusi@gmail.com> Signed-off-by: Sudip Mukherjee <sudip@vectorindia.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2015-03-16Staging: rtl8712: Eliminate use of _cancel_timer_exVaishali Thakkar
Use timer API function del_timer_sync instead of driver specific function _cancel_timer_ex as besides deactivating a timer, it ensures that the timer is stopped on all CPUs before the driver exists. Also, definition of function _cancel_timer_ex 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; @@ - _cancel_timer_ex (&x); + del_timer_sync (&x); Signed-off-by: Vaishali Thakkar <vthakkar1994@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2015-03-06Staging: rtl8712: Eliminate use of _init_timerVaishali Thakkar
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>
2014-10-29staging: rtl8712: remove unused variablesSudip Mukherjee
unused variables are removed. These variables were only assigned some values and after that they were never being used. So they are safe to be removed , and it has been build tested. I left a call to r8712_read32(padapter, TCR) and r8712_read8(padapter, SDIO_HCPWM) . r8712_read32() and r8712_read8() is ultimately calling usb_read32() and usb_read8() respectively. and they are again calling r8712_usbctrl_vendorreq(). this r8712_usbctrl_vendorreq() is communicating through the usb bus and is sending and receiving the control msg.

2014-07-09staging: rtl8712: remove wrapper function _set_workitem()James A Shackleford
The inline function _set_workitem() simply wraps schedule_work(). Removed. Signed-off-by: James A Shackleford <shack@linux.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-07-09staging: rtl8712: remove wrapper function _init_workitem()James A Shackleford
The inline function _init_workitem() is just a wrapper around INIT_WORK(). Oddly, this wrapper accepts 3 parameters while INIT_WORK() only accepts 2. The third parameter is unused. Signed-off-by: James A Shackleford <shack@linux.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-02-09staging: r8712u: Simplify semaphoresLarry Finger
I am preparing to convert this driver from semaphore to mutex locking, The first step has been to eliminate a number of semaphores that were initialized but never used, and one whose only use was a single "up" after initialization. A total of 9 semaphores were removed in this process. One other change was to remove some inline semaphore routines that were unused. In addition, several cases had the following structure: down() if () { ... } up() The locking overhead was reduced by moving the up/down inside the if block.

2010-08-20staging: r8712u: Add the new driver to the mainline kernelLarry Finger
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.
