2016-09-03rtl8xxxu: Simplify calculating of hw value used for setting TX rateJes Sorensen
Calculating the value in one place rather than using one calculation in one place and a different one for management frames in another location makes little sense. Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2016-09-03rtl8xxxu: Use flag to indicate whether device has TX report timer supportJes Sorensen
Use a fileops flag to indicate whether the device has TX report timer support. This will make it easier to include future devices such as 8188eu to use the TX report timer. Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2016-09-03rtl8xxxu: Switch 8723a to use new rtl8xxxu_init_queue_reserved_page() routineJes Sorensen
This changes the pub-queue value written to REQ_RQPN, however the old code used a hard coded minimum value assuming there would always be an active lo-queue, even when no USB EP was found for it. Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2016-09-03wlcore: Remove wl pointer from wl_sta structureMaxim Altshul
This field was added to wl_sta struct to get hw in situations where it was not given to driver by mac80211. In our case, get_expected_throughput op did not send hw to driver. This patch reverts the change, as it is no longer needed due to commit 4fdbc67a25ce ("mac80211: call get_expected_throughput only after adding station") as hw is now sent as a parameter.

2016-09-03iio: accel: bmc150: reset chip at init timeOlof Johansson
In at least one known setup, the chip comes up in a state where reading the chip ID returns garbage unless it's been reset, due to noise on the wires during system boot. All supported chips have the same reset method, and based on the datasheets they all need 1.3 or 1.8ms to recover after reset. So, do the conservative thing here and always reset the chip.

2016-09-03spi: Prevent unexpected SPI time out due to arithmetic overflowSien Wu
When reading SPI flash as MTD device, the transfer length is directly passed to the spi driver. If the requested data size exceeds 512KB, it will cause the time out calculation to overflow since transfer length is 32-bit unsigned integer. This issue is resolved by using 64-bit unsigned integer to perform the arithmetic.
