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 ...

When fe_ops.read_status is called and no channel is tuned (yet), the subsequent calls to get_lock_status() causes the kernel log to be filled with drxk: Error -22 on get_lock_status which either means a NULL pointer was passed for the p_lock_status var, or neither QAM nor OFDM/DVBT operation mode are active. Instead of filling the kernel log in the latter case, print out a message to the debug level and return 0 (this isn't used in the calling drxk_get_stats() anyway).

So don't divide by the result of dib7000p_get_internal_freq() without checking it for zero in dib7000p_set_dds(). On one of my machines the device ID 2304:0229 Pinnacle Systems, Inc. PCTV Dual DVB-T 2001e about once a day/every two days gets into a state, where most (all?) I2C reads return with an error. Tuning during this state will result in a divide by zero without this patch.

There is only 2 extra registers, 0x32 and 0x36 on bank2, that are programmed for DVB-T2 but not for DVB-T and all the rest are programmed similarly - so it is likely PLP.

2016-11-23[media] stv090x: use lookup tables for carrier/noise ratioJoerg Riechardt
The stv090x driver uses the lookup table for signal strength already, with this patch we use the lookup tables for carrier/noise ratio as well. This has the advantage, that values for DVB-S and DVB-S2 are now corresponding, while before they were way off. The values are now proportional to real carrier/noise ratio, while before they were corresponding to register values. So now applications are able to give the user real carrier/noise ratio. Because the output has to be within 0x0000...0xFFFF the three negative values for DVB-S2 are omitted. This is no significant loss, because reception is lost at 7.5 dB already (TT S2-1600, Cine S2), so the negative values are not really important, and also for DVB-S they don´t exist.

Note: as the argument for the release ops changed from "int" to "void", we needed to change it at the revert patch, to avoid compilation issues like: drivers/media/tuners/tea5767.c:437:23: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types] .release = tea5767_release, ^~~~~~~~~~~~~~~ This reverts commit 22a613e89825ea7a3984a968463cc6d425bd8856.

2016-11-18[media] Kconfig: fix breakages when DVB_CORE is not selectedMauro Carvalho Chehab
On some weird randconfigs, it is possible to select DVB drivers, without having the DVB_CORE: CONFIG_DVB_AU8522=m CONFIG_DVB_AU8522_V4L=m CONFIG_DVB_TUNER_DIB0090=m This was never supposed to work, but changeset 22a613e89825 ("[media] dvb_frontend: merge duplicate dvb_tuner_ops.release implementations") caused it to be exposed: drivers/built-in.o: In function `fc0011_attach': (.text+0x1598fb): undefined reference to `dvb_tuner_simple_release' drivers/built-in.o:(.rodata+0x55e58): undefined reference to `dvb_tuner_simple_release' drivers/built-in.o:(.rodata+0x57398): undefined reference to `dvb_tuner_simple_release' Fixes: 22a613e89825 ("[media] dvb_frontend: merge duplicate dvb_tuner_ops.release implementations") Reported-by: kbuild test robot <fengguang.wu@intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

2016-11-18[media] dvb_frontend: tuner_ops.release returns voidMax Kellermann
It is not clear what this return value means. All implemenations return 0, and the one caller ignores the value. Let's remove this useless return value completely. Signed-off-by: Max Kellermann <max.kellermann@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-11-18[media] dvb_frontend: merge duplicate dvb_tuner_ops.release implementationsMax Kellermann
Most release callback functions are identical: free the "tuner_priv" and clear it. Let's eliminate some bloat by providing this simple implementation in the dvb_frontend library. Signed-off-by: Max Kellermann <max.kellermann@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-11-18[media] dvb: make DVB frontend *_ops instances "const"Max Kellermann
These are immutable. Making them "const" allows the compiler to move them to the "rodata" section. Note that cxd2841er_t_c_ops cannot be made "const", because cxd2841er_attach() modifies it. Ouch!

2016-11-18[media] dibx000_common: use pr_foo() instead of printk()Mauro Carvalho Chehab
The dprintk() macro relies on continuation lines. This is not a good practice and will break after commit 563873318d32 ("Merge branch 'printk-cleanups'"). So, instead of directly calling printk(), use pr_foo() macros, adding a \n leading char on each macro call. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
