The device ->submit_io() callback might fail to submit I/O to device. In that case, the nvm_submit_ppa function should not wait for completion. Instead return the ->submit_io() error.

2016-05-06remoteproc: core: Task sync during rproc_fw_boot()Lee Jones
By default, rproc_fw_boot() needs to wait for rproc to be configured, but a race may occur when using rpmsg/virtio. In this case, it can be called locally in a safe manor. This patch represents two usecases: - External call (via exported rproc_boot()), which waits - Internal call can use 'nowait' version of rproc_boot() Signed-off-by: Fabrice Gasnier <fabrice.gasnier@st.com> Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2016-05-06[media] v4l2-ioctl.c: improve cropcap compatibility codeHans Verkuil
- Add a check for the case that both the cropcap and g_selection ops are NULL. This shouldn't happen, but I feel happier if the code guards against this. - If g_selection exists, then ignore ENOTTY and ENOIOCTLCMD error codes from cropcap. Just assume square pixelaspect ratio in that case. This situation can happen if the bridge driver's cropcap op calls the corresponding subdev's op. So the cropcap ioctl is set, but it might return ENOIOCTLCMD anyway. In the past this would just return an error which is wrong. - Call cropcap first and let g_selection overwrite the bounds and defrect. This safeguards against subdev cropcap implementations that set those rectangles as well. What g_selection returns has priority over what such cropcap implementations return.

2016-05-06ath10k: update bss channel survey informationRajkumar Manoharan
During hw scan, firmware sends two channel information events (pre- complete, complete) to host for each channel change. The snap shot of cycle counters (rx_clear and total) between these two events are given for survey dump. In order to get latest survey statistics of all channels, a scan request has to be issued. In general, an AP DUT is brought up, it won't leave BSS channel except few cases like overlapping bss or radar detection. So survey statistics of bss channel is always referring to older data that are collected before starting AP (either ACS/OBSS scan). To collect latest survey information from target, firmware provides WMI interface to read cycle counters from hardware. For each survey dump request, BSS channel cycle counters are read and cleared in hardware. This makes sure that behavior is in align with ath9k survey report. So survey dump always gives snap shot of cycle counters b/w two survey requests.

There are vendor extensions to allow a subset of VHT to work (notably 256-QAM), but since mac80211 doesn't support those advertising VHT capability on 2.4GHz leads to the behaviour of reporting VHT capabilities but not being able to use any of them due to mac80211's code requiring 80 MHz support.

2016-05-06cpufreq: governor: Fix handling of special cases in dbs_update()Rafael J. Wysocki
As reported in KBZ 69821: "With CONFIG_HZ_PERIODIC=y cpu stays at the lowest frequcency 800MHz even if usage goes to 100%, frequency does not scale up, the governor in use is ondemand. Neither works conservative. Performance and userspace governors work as expected. With CONFIG_NO_HZ_IDLE or CONFIG_NO_HZ_FULL cpu scales up with ondemand as expected." Analysis carried out by Chen Yu leads to the conclusion that the observed issue is due to idle_time in dbs_update() representing a negative number in which case the function will return 0 as the load (unless load is greater than 0 for another CPU sharing the policy), although that need not be the right choice. Indeed, idle_time representing a negative number means that during the last sampling interval the CPU was almost 100% busy on the rough average, so 100 should be returned as the load in that case. Modify the code accordingly and rearrange it to clarify the handling of all of the special cases in it. While at it, also avoid returning zero as the load if time_elapsed is 0 (it doesn't really make sense to return 0 then).

2016-05-06[media] zl10353: use div_u64 instead of do_divArnd Bergmann
Using div_u64() instead of do_div() makes the code slightly more readable by humans. [mchehab@osg.samsung.org: originally, this patch was proposed as a bug fix for a gcc bug. This was solved already, but it is still better to use div_u64, instead of do_div, so I'm applying it, removing the comments about the gcc bug] Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

2016-05-06PM / OPP: Move CONFIG_OF dependent code in a separate fileViresh Kumar
Recently, a few issues were noticed in the code where CONFIG_OF wasn't consistently used for many routines. The core file is big enough now and ifdef hackery makes it less readable. Move OF-specific code to another file and compile that only if CONFIG_OF is enabled. Compile-tested: - For ARM (exynos) with CONFIG_OF enabled - For X86 with CONFIG_OF disabled (have to enable CONFIG_PM_OPP separately) No functional changes.
