2017-04-13rtlwifi: btcoex: 23b 2ant: check PS state before setting tdma durationYan-Hsuan Chuang
For time division multiple access, the wifi and bt take turns to transmit, but we need to let AP know that wifi is under standby mode by sending null data to "pretend" entering power saving state using lps rpwm. But, the fw does not know if it is the actual power saving mode or just a fake one to cheat to the AP. Hence, before fw setting the tdma duration, the fw needs the driver to check the power saving state first.

2017-02-27scripts/spelling.txt: add "aligment" pattern and fix typo instancesMasahiro Yamada
Fix typos and add the following to the scripts/spelling.txt: aligment||alignment I did not touch the "N_BYTE_ALIGMENT" macro in drivers/net/wireless/realtek/rtlwifi/wifi.h to avoid unpredictable impact. I fixed "_aligment_handler" in arch/openrisc/kernel/entry.S because it is surrounded by #if 0 ... #endif. It is surely safe and I confirmed "_alignment_handler" is correct. I also fixed the "controler" I found in the same hunk in arch/openrisc/kernel/head.S.

2017-02-08rtlwifi: Move items out of rtl_pci_priv and rtl_usb_privLarry Finger
In commit 6773386f977c ("rtlwifi: rtl8192c-common: Fix "BUG: KASAN:"), a BUG detected when CONFIG_KASAN=y was fixed by reordering the layouts of struct rtl_pci_priv, and struct rtl_usb_priv so that the variables used by both PCI and USB drivers have the same offsets in both structs. The better fix of relocating the critical variables into struct rtl_priv was deferred as these changes do not have to be applied to stable kernels. This change also removes CamelCase variables with pLed0 => pled0. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
