Correct one coding style problem(detected by checkpatch.pl) in pcl818.c. - code indent should use tabs where possible It is fixed by reformatting the comment block to usual comment style. And with the reformatting, following coding style problem is also fixed: - please, no space before tabs Signed-off-by: Simon Guo <wei.guo.simon@gmail.com> Reviewed-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

The unlocked_ioctl handler in "comedi_fops.c" calls a different function to handle each supported ioctl command code. Most of these have a block comment indicating which command code it handles, a brief description, and an informal description of the inputs and outputs. These block comments were formatted in various styles, but have been reformatted to use the usual block comment style. The block comment for the handler function for the `COMEDI_RANGEINFO` ioctl code is in "range.c". Reformat it to use the usual block command style to match the others.

The private data 'pm', 'pt', and 'pp' array members hold the trigger mode parameters for ports A and B. Both ports are 8-bits and the arrays are 16-bits. Array index 0 defines the AND mode and index 1 the OR mode parameters for both ports. The valid triggers to start the async command are 0 to 3 which select the AND/OR mode for each port. The 'pb_trig' (the array index for port B) in apci1500_di_inttrig_start() is incorrect and results in an index of 0 or 2. Fix the calc so that the correct index (0/1) is used.

The I2O layer deals with a technology that to say the least didn't catch on in the market. The only relevant products are some of the AMI MegaRAID - which supported I2O and its native mode (The native mode is faster and runs on Linux), an obscure crypto ethernet card that's now so many years out of date nobody would use it, the old DPT controllers, which speak their own dialect and have their own driver - and ermm.. thats about it. We also know the code isn't in good shape as recently a patch was proposed and queried as buggy, which in turn showed the existing code was broken already by prior "clean up" and nobody had noticed that either. It's coding style robot code nothing more. Like some forgotten corridor cleaned relentlessly by a lost Roomba but where no user has trodden in years. Move it to staging and then to /dev/null. The headers remain as they are shared with dpt_i2o. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Commit 8eb23b9f ("sched: Debug nested sleeps") added code to report on nested sleep conditions, which we generally want to avoid because the inner sleeping operation can re-set the thread state to TASK_RUNNING, but that will then cause the outer sleep loop not actually sleep when it calls schedule. However, that's actually valid traditional behavior, with the inner sleep being some fairly rare case (like taking a sleeping lock that normally doesn't actually need to sleep). And the debug code would actually change the state of the task to TASK_RUNNING internally, which makes that kind of traditional and working code not work at all, because now the nested sleep doesn't just sometimes cause the outer one to not block, but will cause it to happen every time. In particular, it will cause the cardbus kernel daemon (pccardd) to basically busy-loop doing scheduling, converting a laptop into a heater, as reported by Bruno Prémont. But there may be other legacy uses of that nested sleep model in other drivers that are also likely to never get converted to the new model. This fixes both cases: - don't set TASK_RUNNING when the nested condition happens (note: even if WARN_ONCE() only _warns_ once, the return value isn't whether the warning happened, but whether the condition for the warning was true. So despite the warning only happening once, the "if (WARN_ON(..))" would trigger for every nested sleep. - in the cases where we knowingly disable the warning by using "sched_annotate_sleep()", don't change the task state (that is used for all core scheduling decisions), instead use '->task_state_change' that is used for the debugging decision itself. (Credit for the second part of the fix goes to Oleg Nesterov: "Can't we avoid this subtle change in behaviour DEBUG_ATOMIC_SLEEP adds?" with the suggested change to use 'task_state_change' as part of the test) Reported-and-bisected-by: Bruno Prémont <bonbons@linux-vserver.org> Tested-by: Rafael J Wysocki <rjw@rjwysocki.net> Acked-by: Oleg Nesterov <oleg@redhat.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Gleixner <tglx@linutronix.de>, Cc: Ilya Dryomov <ilya.dryomov@inktank.com>, Cc: Mike Galbraith <umgwanakikbuti@gmail.com> Cc: Ingo Molnar <mingo@kernel.org> Cc: Peter Hurley <peter@hurleysoftware.com>, Cc: Davidlohr Bueso <dave@stgolabs.net>, Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Merge tag 'iio-for-3.20b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-testing Jonathan writes: Second round of IIO new drivers, functionality and cleanups for the 3.20 cycle. New drivers and device support: * Capella cm3232 ambient light sensor driver. * Freescale MMA9553 pedometer and activity monitor. Note this involved a refactor of the mma9551 driver to pull out shared elements. * Samsung sensor hub (as used in the galaxy gear 2 watch) Core support and initial drivers (gyro and accelerometer) more to follow. An additional fix was applied on top of this for a build issue thrown up by the autobuilders on some platforms. * Cosmic Circuits 10001 ADC driver * Qualcomm SPMI PMIC voltage ADC driver (current adc merged a while back). * Add binding for AK8963 (in capitals) as unfortunately there are bios' out there not using lower case. New functionality * Add newe operating mode to the core to allow for non triggered software buffers. This is mostly semantics as previously drivers just claimed they had a hardware buffer (when they didn't). * Add distance channel type. * Add energy channel type. * Add velocity channel type and IIO_MOD_ROOT_SUM_SQUARED (i.e. speed when our channel type is velocity). * Add _debounce_count and _debounce_time filter attributes. Only really make sense for counting types of measurements. First use is for avoiding miss detection of steps prior to walking. * Add change event type. This replaces the briefly present INSTANCE type (which hadn't gained any users). It is more generic as it allows for events say every 10 steps rather than every step. * Add _calibweight attributes to the ABI (and core support). Used by activity monitors to estimate energy use. Can imagine there will be other uses for this one. Driver new functionality * mma9551 gains runtime pm support. * hid-sensors gain PM support. Cleanup * Change calibheight unit to m from cm. As there are no prior users and this was inconsistent with other distance units, it makes sense to fix it before hte mma9553 driver which uses it. * mpu6050 cleanups and devm_ use. * as3935 switch over to PM ops. * Fix a few format strings for signed vs unsigned. * Fix tcs3414 missindentation * Typo in industrialio-event * Stop requiring IIO_TRIGGER for IIO_KFIFO_BUF as we have drivers that don't need it. No one is quite sure why that dependency was there and it seems to not matter.
