staging/lustre/llite: fix ll_getname user buffer copy
strncpy_from_user could return negative values on error,
so need to take those into account.
Since ll_getname is used to get a single component name from userspace
to transfer to server as-is, there's no need to allocate 4k buffer
as done by __getname. Allocate NAME_MAX+1 buffer instead to ensure
we have enough for a null terminated max valid length buffer.
This was discovered by Al Viro in https://lkml.org/lkml/2015/4/11/243
It uses getname in unsafe manner and since it's to deal with corrupted
or inconsistent filesystem, we are probably better to deal with
it from lfsck anyway.

Jonathan writes:
Third round of new IIO drivers, cleanups and functionality for the 4.2 cycle.
Given Linus announced a 4.8rc coming up, hopefully time for one more
lot of IIO patches this cycle. Some of these are actually
improvements / fixes for patches earlier in the cycle.
New device support
* st_accel driver - support devices with 8 bit channels.
Cleanup
* A general cleanup of the iio tools under /tools/ from Hartmut.
I'm more than a little embarassed by how bad some of these were! Are well,
much more refined and less bug prone now.
These cover lots of stuff like unhandled error returns, memory leaks as
well as general refactoring to tidy the code up.
* iio_simple_dummy - fix memory leaks in the init functions, drop some
pointless error returns from functions that never generate errors and
make the module parameter explicitly unsigned.
* More buffer handling reworks from Lars-Peter, this time targetting hardware
buffers (a little used corner that looks likely to get more use in the near
future). Specifically:
- Always compute the masklength as inkernel buffer users may need it.
- Add a means of labeling which buffer modes a given buffer implementation
supports.
- In the case of hardware buffers, require strict scan matching rather than
matching to a superset. Currently the demux is bypassed by these drivers
(this may well not change for efficiency reasons) so allowing a superset
of channels to be selected would otherwise lead to more data than requested
confusing userspace.
Driver funcationality improvments
* mmc35240 - adds a compensation to the raw values as borrowed form Memsic's
own input driver.
* mma8452
- event support
- event debouncing
- high pass filter configuration
- triggers
* vf610 - allow conversion mode to be adjusted
Fixlets
* mmc35240
- Off by one error that by coincidence had no real effect.
- i2c_device_name should be lowercase.
- Lack of null terminator at end of attributes array.
- Avoid computing the fractional part of the magnetic field by moving
the scaling into userspace where floating point is available to simplify
the maths.
- Use a smaller sleep before assuming the measurement is done. This is
safe and improves the possible polling rate.
- Fix sensitivity on z-axis - datasheet disagrees with Memsic's releasedd
code and the value used in the code seems to be correct.
* stk3310 - make a local variable signed to ensure error handling works.
* twl4030
- fix calculation of the temperature sense current - bug unlikely
to have ever been noticed as the difference is small.
- Fix errors in descriptions.
