2017-12-02brcmfmac: change driver unbind order of the sdio function devicesArend Van Spriel
In the function brcmf_sdio_firmware_callback() the driver is unbound from the sdio function devices in the error path. However, the order in which it is done resulted in a use-after-free issue (see brcmf_ops_sdio_remove() in bcmsdh.c). Hence change the order and first unbind sdio function #2 device and then unbind sdio function #1 device. Cc: stable@vger.kernel.org # v4.12.x Fixes: 7a51461fc2da ("brcmfmac: unbind all devices upon failure in firmware callback") Reported-by: Stefan Wahren <stefan.wahren@i2se.com> Reviewed-by: Hante Meuleman <hante.meuleman@broadcom.com> Reviewed-by: Pieter-Paul Giesberts <pieter-paul.giesberts@broadcom.com> Reviewed-by: Franky Lin <franky.lin@broadcom.com> Signed-off-by: Arend van Spriel <arend.vanspriel@broadcom.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2017-12-02wcn36xx: set default BTLE coexistence configEyal Ilsar
If the value for the firmware configuration parameters BTC_STATIC_LEN_LE_BT and BTC_STATIC_LEN_LE_WLAN are not set the duty cycle between BT and WLAN is such that if BT (including BLE) is active WLAN gets 0 bandwidth. When tuning these parameters having a too high value for WLAN means that BLE performance degrades. The "sweet" point of roughly half of the maximal values was empirically found to achieve a balance between BLE and Wi-Fi coexistence performance.

It is required to update the teardown state of the peer when a tdls link with that peer is terminated. This information is useful for the target to perform some cleanups wrt the tdls peer. Without proper cleanup, target assumes that the peer is connected and blocks future connection requests, updating the teardown state of the peer addresses the problem.

Commit 4ca1807815aa ("ath10k: disable wake_tx_queue for older devices") disables the use of the mac80211 TXQs for some devices because of a theoretical throughput regression. The original regression report[1] was related to fq_codel qdisc drop performance, which was fixed in commit 9d18562a2278 ("fq_codel: add batch ability to fq_codel_drop()"). Since then, we have not seen the TXQ-related regression, so it should be safe to re-enable TXQs.

2017-12-02iio: stm32: fix adc/trigger link errorArnd Bergmann
The ADC driver can trigger on either the timer or the lptim trigger, but it only uses a Kconfig 'select' statement to ensure that the first of the two is present. When the lptim trigger is enabled as a loadable module, and the adc driver is built-in, we now get a link error: drivers/iio/adc/stm32-adc.o: In function `stm32_adc_get_trig_extsel': stm32-adc.c:(.text+0x4e0): undefined reference to `is_stm32_lptim_trigger' We could use a second 'select' statement and always have both trigger drivers enabled when the adc driver is, but it seems that the lptimer trigger was intentionally left optional, so it seems better to keep it that way. This adds a hack to use 'IS_REACHABLE()' rather than 'IS_ENABLED()', which avoids the link error, but instead leads to the lptimer trigger not being used in the broken configuration. I've added a runtime warning for this case to help users figure out what they did wrong if this should ever be done by accident.

2017-12-02iio: adc: meson-saradc: fix the bit_idx of the adc_en clockMartin Blumenstingl
Meson8 and Meson8b SoCs use the the SAR ADC gate clock provided by the MESON_SAR_ADC_REG3 register within the SAR ADC register area. According to the datasheet (and the existing MESON_SAR_ADC_REG3_CLK_EN definition) the gate is on bit 30. The fls() function returns the last set bit, which is "bit index + 1" (fls(MESON_SAR_ADC_REG3_CLK_EN) returns 31). Fix this by switching to __ffs() which returns the first set bit, which is bit 30 in our case. This off by one error results in the ADC not being usable on devices where the bootloader did not enable the clock.

2017-12-01RISC-V: Fixes for clean allmodconfig buildPalmer Dabbelt
Olaf said: Here's a short series of patches that produces a working allmodconfig. Would be nice to see them go in so we can add build coverage. I've dropped patches 8 and 10 from the original set: * [PATCH 08/10] (RISC-V: Set __ARCH_WANT_RENAMEAT to pick up generic version) has a better fix that I've sent out for review, we don't want renameat. * [PATCH 10/10] (input: joystick: riscv has get_cycles) has already been taken into Dmitry Torokhov's tree.

2017-12-01RISC-V: User-Visible ChangesPalmer Dabbelt
This merge contains the user-visible, ABI-breaking changes that we want to make sure we have in Linux before our first release. Highlights include: * VDSO entries for clock_get/gettimeofday/getcpu have been added. These are simple syscalls now, but we want to let glibc use them from the start so we can make them faster later. * A VDSO entry for instruction cache flushing has been added so userspace can flush the instruction cache. * The VDSO symbol versions for __vdso_cmpxchg{32,64} have been removed, as those VDSO entries don't actually exist. Conflicts: arch/riscv/include/asm/tlbflush.h
2017-12-01RISC-V Atomic CleanupsPalmer Dabbelt
This patch set is the result of some feedback that filtered through after our original patch set was reviewed, some of which was the result of me missing some email. It contains: * A new READ_ONCE in arch_spin_is_locked() * __test_and_op_bit_ord() is now actually ordered * Improvements to various comments * Removal of some dead code
