2017-05-05Merge tag 'staging-4.12-rc1' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging Pull staging/IIO updates from Greg KH: "Here is the big staging tree update for 4.12-rc1. It's a big one, adding about 350k new lines of crap^Wcode, mostly all in a big dump of media drivers from Intel. But there's other new drivers in here as well, yet-another-wifi driver, new IIO drivers, and a new crypto accelerator. We also deleted a bunch of stuff, mostly in patch cleanups, but also the Android ION code has shrunk a lot, and the Android low memory killer driver was finally deleted, much to the celebration of the -mm developers. All of these have been in linux-next with a few build issues that will show up when you merge to your tree" Merge conflicts in the new rtl8723bs driver (due to the wifi changes this merge window) handled as per linux-next, courtesy of Stephen Rothwell. * tag 'staging-4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (1182 commits) staging: fsl-mc/dpio: add cpu <--> LE conversion for dpaa2_fd staging: ks7010: remove line continuations in quoted strings staging: vt6656: use tabs instead of spaces staging: android: ion: Fix unnecessary initialization of static variable staging: media: atomisp: fix range checking on clk_num staging: media: atomisp: fix misspelled word in comment staging: media: atomisp: kmap() can't fail staging: atomisp: remove #ifdef for runtime PM functions staging: atomisp: satm include directory is gone atomisp: remove some more unused files atomisp: remove hmm_load/store/clear indirections atomisp: kill off mmgr_free atomisp: clean up the hmm init/cleanup indirections atomisp: handle allocation calls before init in the hmm layer staging: fsl-dpaa2/eth: Add maintainer for Ethernet driver staging: fsl-dpaa2/eth: Add TODO file staging: fsl-dpaa2/eth: Add trace points staging: fsl-dpaa2/eth: Add driver specific stats staging: fsl-dpaa2/eth: Add ethtool support staging: fsl-dpaa2/eth: Add Freescale DPAA2 Ethernet driver ...
2017-04-28staging: wilc1000: fix unchecked return valuePan Bian
Function dev_alloc_skb() will return a NULL pointer if there is no enough memory. However, in function WILC_WFI_mon_xmit(), its return value is used without validation. This may result in a bad memory access bug. This patch fixes the bug. Signed-off-by: Pan Bian <bianpan2016@163.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2017-04-13cfg80211: move add/change interface monitor flags into paramsJohannes Berg
Instead passing both flags, which can be NULL, and vif_params, which are never NULL, move the flags into the vif_params and use BIT(0), which is invalid from userspace, to indicate that the flags were changed. While updating all drivers, fix a small bug in wil6210 where it was setting the flags to 0 instead of leaving them unchanged. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2017-04-08staging: wilc1000: fix incorrect strncasecmp lengthColin Ian King

2017-04-08staging: wilc1000: Fix problem with wrong vif indexAditya Shankar
The vif->idx value is always 0 for two interfaces. wl->vif_num = 0; loop { ... vif->idx = wl->vif_num; ... wl->vif_num = i; .... i++; ... } At present, vif->idx is assigned the value of wl->vif_num at the beginning of this block and device is initialized based on this index value. In the next iteration, wl->vif_num is still 0 as it is only updated later but gets assigned to vif->idx in the beginning. This causes problems later when we try to reference a particular interface and also while configuring the firmware. This patch moves the assignment to vif->idx from the beginning of the block to after wl->vif_num is updated with latest value of i.

Not as big as 4.9 was, but still just over a thousand changes.
