2016-06-18staging/android: sync_debug: unproxify debugfs files' fopsNicolai Stange1-4/+9
Since commit 49d200deaa68 ("debugfs: prevent access to removed files' private data"), a debugfs file's file_operations methods get proxied through lifetime aware wrappers. However, only a certain subset of the file_operations members is supported by debugfs and ->compat_ioctl isn't among them -- it appears to be NULL from the VFS layer's perspective. This behaviour breaks the /sys/kernel/debug/sync/sw_sync file introduced concurrently with commit a44eb74cd413 ("staging/android: move SW_SYNC_USER to a debugfs file"). Since that file never gets removed, there is no file removal race and thus, a lifetime checking proxy isn't needed. Avoid the proxying for /sys/kernel/debug/sync/sw_sync by creating it via debugfs_create_file_unsafe() rather than debugfs_create_file(). For consistency, do the same for /sys/kernel/debug/sync/info.

2016-06-18staging: comedi: avoid using timevalArnd Bergmann1-4/+5
Comedi uses 32-bit seconds for its timestamps, on both 32-bit and 64-bit machines. For all I can tell, this was originally meant as a 'timespec', which would overflow in 2038 because of the use of a signed 'long' on 32-bit machines, but it is now used as an array of two unsigned 'lsampl_t' values in comedilib, which will only overflow in 2106, on both 32-bit and 64-bit machines. In an effort to get rid of all uses of 'struct timeval' in the kernel, this replaces the internal code with a call to ktime_get_real_ts64() and a comment at the location of the conversion.

2016-06-18staging: comedi: addi_apci_1564: clarify change-of-state interrupt supportH Hartley Sweeten1-12/+29
This board supports change-of-state interrupts on digital inputs 4 to 19 not 0 to 15. The current code "works" but it could set inappropriate bits in the mode1 and mode2 registers that setup which channels are enabled. It also doesn't return the status of the upper 4 channels (19 to 16). Fix the comment and mask the mode1/mode2 values so that only the interrupt capable channels can be enabled. Add the SDF_LSAMPL flag to the subdevice so that 32-bit samples are used instead of 16-bit ones. This allows returning the upper 4 channels. Use the remaining bits in the sample to return "event" flags to the user. The timer and counter subdevices can also generate interrupts and are a bit hacked. They don't currently follow the comedi API and they use send_sig() to let the task that know that the interrupt occured. The "event" flags will be used instead when these subdevices are fixed.

2016-06-18staging: comedi: plx9080.h: tidy up some commentsIan Abbott1-24/+12
Use the usual block comment style and remove some excess spaces from single-line comments. Remove some obvious stuff about register offsets being zero relative. Remove some text about the original history of the file, as it bears hardly any resemblance to it now.

2016-06-18staging: comedi: drivers: add PLX PCI 9080 DMATHR register valuesIan Abbott1-0/+41
Add macros in "plx9080.h" that define values for the DMATHR register values. Use the prefix `PLX_DMATHR_` for the macros. Make use of the `BIT(x)` and `GENMASK(h,l)` macros to define the values.
