From bcfb879432094c267c35a7ff75d953d3a66c193a Mon Sep 17 00:00:00 2001 From: Larry Finger Date: Fri, 28 Jun 2013 09:12:53 -0500 Subject: [PATCH 1/8] rtlwifi: Initialize power-setting callback for USB devices Commit a269913c5 entitled "rtlwifi: Rework rtl_lps_leave() and rtl_lps_enter() to use work queue" has two bugs for USB drivers. Firstly, the work queue in question was not initialized. Secondly, the callback routine used by this queue is contained within the file used for PCI devices. As a result, it is not available for architectures without PCI hardware.

In particular, ath9k_hif_usb_firmware_cb() callback initializes hif_dev->tx.tx_buf and hif_dev->tx.tx_pending lists. At the same time, ath9k_hif_usb_suspend() iterates that lists through ath9k_hif_usb_dealloc_urbs(). If suspend happens before request_firmware_nowait() callback is called, it can lead to oops. Similar issue could be in ath9k_hif_usb_disconnect(), but it is prevented using hif_dev->fw_done completion and HIF_USB_READY flag. The patch extends this approach to suspend() as well.

(2) If the PCI drivers are built into the kernel and the USB drivers are modules, or vice versa, there are missing globals. The first condition is fixed by never building rtlwifi unless at least one of the device drivers is selected. The second failure is fixed by splitting the PCI and USB codes out of rtlwifi, and creating their own mini drivers. If the drivers that use them are modules, they will also be modules. Although a number of files are touched by this patch, only Makefile and Kconfig have undergone significant changes. The only modifications to the other files were to export entry points needed by the new rtl_pci and rtl_usb units, or to rename two variables that had names that were likely to cause namespace collisions.
