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. Signed-off-by:Vaibhav Gupta <vaibhavgupta40@gmail.com> Signed-off-by:

Missing this firmware is not fatal, my wifi card still works. Even more, I couldn't find any documentation what it is or where to get it. So, I don't think the users should be notified if it is missing. If you browse the net, you see the message is present is in quite some logs. Better remove it. Signed-off-by:

Without this patch, RTL8821CE will not have coex support, and will crash the system because of the NULL pointers for the coex functions. While RTL8822C series are WiFi + BT combo chips, it needs the co-existence mechanism for the device to work on both WiFi and BT without interfering each other. And the coex support has already been added before, most of the mechanisms are implemented. The driver should just add corresponding functions to operate on different types of chips and its coex parameters. Fixes: f745eb9c ("rtw88: 8821c: Add 8821CE to Kconfig and Makefile") Signed-off-by:

The coex mechanism used to skip upon the freeze flag is raised. That will cause the coex mechanism being skipped unexpectedly. Coex only wanted to keep the TDMA table from being changed by BT side. So, check the freeze and reason, if the coex reason is coming from BT info, skip it, to make sure the coex triggered by Wifi itself can work. This is required for the AP mode, while the control flow is different with STA mode. When starting an AP mode, the AP mode needs to start working immedaitely after leaving IPS, and the freeze flag could be raised. If the coex info is skipped, then the AP mode will not set the antenna owner, leads to TX stuck. Fixes: 4136214f ("rtw88: add BT co-existence support") Signed-off-by:

Fix the transmission is not sent with short GI under some conditions even if the receiver supports short GI. If VHT capability IE exists in the beacon, the original code uses the short GI for 80M field as driver's short GI setting for transmission, even the current bandwidth is not 80MHz. Short GI supported fields for 20M/40M are informed in HT capability information element, and short GI supported field for 80M is informed in VHT capability information element. These three fields may be set to different values. Driver needs to record each short GI support field for each bandwidth, and send correct info depends on current bandwidth to the WiFi firmware.

Drivers using legacy power management .suspen()/.resume() callbacks have to manage PCI states and device's PM states themselves. They also need to take care of standard configuration registers. Switch to generic power management framework using a single "struct dev_pm_ops" variable to take the unnecessary load from the driver. This also avoids the need for the driver to directly call most of the PCI helper functions and device power state control functions as through the generic framework, PCI Core takes care of the necessary operations, and drivers are required to do only device-specific jobs.

l2tp_session_free called BUG_ON if the tunnel magic feather value wasn't correct. The intent of this was to catch lifetime bugs; for example early tunnel free due to incorrect use of reference counts. Since the tunnel magic feather being wrong indicates either early free or structure corruption, we can avoid doing more damage by simply leaving the tunnel structure alone. If the tunnel refcount isn't dropped when it should be, the tunnel instance will remain in the kernel, resulting in the tunnel structure and socket leaking. Signed-off-by:

l2tp_session_queue_purge is used during session shutdown to drop any skbs queued for reordering purposes according to L2TP dataplane rules. The BUG_ON in this function checks the session magic feather in an attempt to catch lifetime bugs. Rather than crashing the kernel with a BUG_ON, we can simply WARN_ON and refuse to do anything more -- in the worst case this could result in a leak. However this is highly unlikely given that the session purge only occurs from codepaths which have obtained the session by means of a lookup via. the parent tunnel and which check the session "dead" flag to protect against shutdown races. While we're here, have l2tp_session_queue_purge return void rather than an integer, since neither of the callsites checked the return value. Signed-off-by:

checkpatch advises that WARN_ON and recovery code are preferred over BUG_ON which crashes the kernel. l2tp_ppp has a BUG_ON check of struct seq_file's private pointer in pppol2tp_seq_start prior to accessing data through that pointer. Rather than crashing, we can simply bail out early and return NULL in order to terminate the seq file processing in much the same way as we do when reaching the end of tunnel/session instances to render.

checkpatch advises that WARN_ON and recovery code are preferred over BUG_ON which crashes the kernel. l2tp_ppp.c's BUG_ON checks of the l2tp session structure's "magic" field occur in code paths where it's reasonably easy to recover: * In the case of pppol2tp_sock_to_session, we can return NULL and the caller will bail out appropriately. There is no change required to any of the callsites of this function since they already handle pppol2tp_sock_to_session returning NULL. * In the case of pppol2tp_session_destruct we can just avoid decrementing the reference count on the suspect session structure. In the worst case scenario this results in a memory leak, which is preferable to a crash. Convert these uses of BUG_ON to WARN_ON accordingly. Signed-off-by:
