* rt2x00: pci: use generic power managementVaibhav Gupta2020-08-021-23/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drivers using legacy PM have to manage PCI states and device's PM states themselves. They also need to take care of configuration registers. With improved and powerful support of generic PM, PCI Core takes care of above mentioned, device-independent, jobs. The callbacks make use of PCI helper functions like pci_save/restore_state(), pci_enable/disable_device() and pci_set_power_state() to do required operations. In generic mode, they are no longer needed. Change function parameter in both .suspend() and .resume() to "struct device*" type. Use dev_get_drvdata() to get drv data. The .suspend() callback is invoking rt2x00lib_suspend() which needs to be modified as generic rt2x00pci_suspend() has no pm_message_t type argument, passed to it, which is required by it according to its declaration. Although this variable remained unused in the function body. Hence, remove it from the function definition & declaration. rt2x00lib_suspend() is also invoked by rt2x00usb_suspend() and rt2x00soc_suspend(). Thus, modify the functional call accordingly in their function body. Earlier, .suspend() & .resume() were exported and were used by the following drivers: - drivers/net/wireless/ralink/rt2x00/rt2400pci.c - drivers/net/wireless/ralink/rt2x00/rt2500pci.c - drivers/net/wireless/ralink/rt2x00/rt2800pci.c - drivers/net/wireless/ralink/rt2x00/rt61pci.c Now, we only need to bind "struct dev_pm_ops" variable to "struct pci_driver". Thus, make the callbacks static. Declare an "extern const struct dev_pm_ops" variable and bind PM callbacks to it. Now, export the variable instead and use it in respective drivers. Compile-tested only.

* rt2x00pci: Disable memory-write-invalidate when the driver exitsJia-Ju Bai2016-01-071-0/+2
| | | | | | | | | | | | | | The driver calls pci_set_mwi to enable memory-write-invalidate when it is initialized, but does not call pci_clear_mwi when it is removed. Many other drivers calls pci_clear_mwi when pci_set_mwi is called, such as r8169, 8139cp and e1000. This patch adds pci_clear_mwi in error handling and removal procedure, which can fix the problem.
