From e29d3ebcda3ebc0193fb98c53c6c3ca6fa2fc030 Mon Sep 17 00:00:00 2001 From: Sudip Mukherjee Date: Mon, 27 Oct 2014 17:42:25 +0530 Subject: staging: rtl8712: remove unused variables 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.
