* rtlwifi: pass struct rtl_stats by reference as it is more efficientColin Ian King2016-03-07
| | | | | | | | | | | passing rtl_stats by value is inefficient; the structure is over 300 bytes in size and generally just one field (packet_report_type) is being accessed, so the pass by value is a relatively large overhead. This change just affects just the rx_command_packet calls.

* rtlwifi: Remove unnecessary synchronize_irq() before free_irq()Lars-Peter Clausen2016-02-25
| | | | | | | | | | | | | | | | | | | | Calling synchronize_irq() right before free_irq() is quite useless. On one hand the IRQ can easily fire again before free_irq() is entered, on the other hand free_irq() itself calls synchronize_irq() internally (in a race condition free way), before any state associated with the IRQ is freed. Patch was generated using the following semantic patch: // <smpl> @@ expression irq; @@ -synchronize_irq(irq); free_irq(irq, ...); // </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Acked-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
* rtlwifi: rtl_pci: Fix kernel panicLarry Finger2015-12-30
| | | | | | | | | | | | | | | | In commit 38506ecefab9 (rtlwifi: rtl_pci: Start modification for new drivers), a bug was introduced that causes a NULL pointer dereference. As this bug only affects the infrequently used RTL8192EE and only under low-memory conditions, it has taken a long time for the bug to show up. The bug was reported on the linux-wireless mailing list and also at https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/ as bug #1527603 (kernel crashes due to rtl8192ee driver on ubuntu 15.10).

* rtlwifi: rtl818x: Move drivers into new realtek directoryLarry Finger2015-10-14
Now that a new mac80211-based driver for Realtek devices has been submitted, it is time to reorganize the directories. Rather than having directories rtlwifi and rtl818x be in drivers/net/wireless/, they will now be in drivers/net/wireless/realtek/. This change simplifies the directory structure, but does not result in any configuration changes that are visable to the user.
