Merge tag 'staging-5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

2019-05-07T20:31:29+00:00

Pull staging / IIO driver updates from Greg KH:
 "Here is the big staging and iio driver update for 5.2-rc1.

  Lots of tiny fixes all over the staging and IIO driver trees here,
  along with some new IIO drivers.

  The "counter" subsystem was added in here as well, as it is needed by
  the IIO drivers and subsystem.

  Also we ended up deleting two drivers, making this pull request remove
  a few hundred thousand lines of code, always a nice thing to see. Both
  of the drivers removed have been replaced with "real" drivers in their
  various subsystem directories, and they will be coming to you from
  those locations during this merge window.

  There are some core vt/selection changes in here, that was due to some
  cleanups needed for the speakup fixes. Those have all been acked by
  the various subsystem maintainers (i.e. me), so those are ok.

  We also added a few new drivers, for some odd hardware, giving new
  developers plenty to work on with basic coding style cleanups to come
  in the near future.

  Other than that, nothing unusual here.

  All of these have been in linux-next for a while with no reported
  issues, other than an odd gcc warning for one of the new drivers that
  should be fixed up soon"

[ I fixed up the warning myself  - Linus ]

staging: kpc2000: fix up build problems with readq()

2019-05-01T08:48:43+00:00

The 0-day system found a bunch of warnings for when readq() is not
defined on the platform, so fix this by including the
linux/io-64-nonatomic-lo-hi.h file which will fix up these issues.

staging: kpc2000: fix resource size calculation

2019-04-30T12:19:04+00:00

The code is calculating the resource size wrong because it should be
inclusive of the "res->end" address.  In other words, "end - start + 1".
We can just use the resource_size() function to do it correctly.

staging: kpc2000: Fix a stack information leak in kp2000_cdev_ioctl()

2019-04-30T12:19:04+00:00

The kp2000_regs struct has a 4 byte hole between ->hw_rev and ->ssid so
this could leak stack information to the user.  This patch just memsets
the whole struct to zero.

staging: kpc2000_spi: eliminated duplicate initialization of master local variable.

2019-04-30T12:19:03+00:00

master was being initialized to a particular value and then having the
same value assigned to it immediately afterwards.  Removed the
initializer.

Since the value assigned to master was dynamically allocated, this fixes
a memory-leak.

staging: kpc2000_spi: eliminated duplicate initialization of drvdata local variable.

2019-04-30T12:19:03+00:00

drvdata was being initialized to a particular value and then
having the same value assigned to it immediately afterwards.  Removed
the initializer.

Since the value assigned, pldev->dev.platform_data, is a pointer-to-
void, removed superfluous cast.

Add Daktronics DMA driver.  I've added the SPDX license identifiers, Kconfig

The AIO support code will be removed in a future patch.
