2017-05-08format-security: move static strings to constKees Cook
While examining output from trial builds with -Wformat-security enabled, many strings were found that should be defined as "const", or as a char array instead of char pointer. This makes some static analysis easier, by producing fewer false positives. As these are all trivial changes, it seemed best to put them all in a single patch rather than chopping them up per maintainer.

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 ...

The final size of the buffer used for the streaming transfer consists of the size for the user payload (buffer_size) and the size for the gaps needed by the controller (extra_len). The current implementation of the hdm_configure_channel() corrects the buffer size down to the next appropriate for the hardware value, that is the whole number of frames, but uses the old unaligned value to calculate the extra_len.

2016-09-22staging: most: make function most_submit_mbo return voidChristian Gromm
Function most_submit_mbo() causes an exception only if either the pointer mbo or mbo->context equals NULL. From the underlying architecture's point of view both cases must _not_ come true and would happen only, if something has tampered with the pointers. This would render runtime code unable to recover anyway. So, instead trying to hide that things are already critically out of control we're better off with a WARN_ON() assertion. This patch replaces the return type of the function most_submit_mbo() with 'void' and adds a WARN_ONCE() assertion. Additionally, code calling the function is adapted accordingly.
