12ca3b20db staging: regulator: hi6421v600-regulator: port it to upstream
The driver was originally written for Kernel 4.9. It needs to
be ported to upstream:

	- Got rid of timeval;
	- Removed a bogus dependency;
	- Did cleanups at the header file.

453431a549 mm, treewide: rename kzfree() to kfree_sensitive()
As said by Linus:

  A symmetric naming is only helpful if it implies symmetries in use.
  Otherwise it's actively misleading.

  In "kzalloc()", the z is meaningful and an important part of what the
  caller wants.

  In "kzfree()", the z is actively detrimental, because maybe in the
  future we really _might_ want to use that "memfill(0xdeadbeef)" or
  something. The "zero" part of the interface isn't even _relevant_.

The main reason that kzfree() exists is to clear sensitive information
that should not be leaked to other future users of the same memory
objects.

Rename kzfree() to kfree_sensitive() to follow the example of the recently
added kvfree_sensitive() and make the intention of the API more explicit.
In addition, memzero_explicit() is used to clear the memory to make sure
that it won't get optimized away by the compiler.

The renaming is done by using the command sequence:

  git grep -w --name-only kzfree |\
  xargs sed -i 's/kzfree/kfree_sensitive/'

followed by some editing of the kfree_sensitive() kerneldoc and adding
a kzfree backward compatibility macro in slab.h.

c0c419c045 Staging/IIO driver patches for 5.9-rc1
Here is the large set of Staging and IIO driver patches for 5.9-rc1.
 
 Lots of churn here, but overall the size increase in lines added is
 small, while adding a load of new IIO drivers.
 
 Major things in here:
 	- lots and lots of IIO new drivers and frameworks added
 	- IIO driver fixes and updates
 	- lots of tiny coding style cleanups for staging drivers
 	- vc04_services major reworks and cleanups
 
 We had 3 set of drivers move out of staging in this round as well:
 	- wilc1000 wireless driver moved out of staging
 	- speakup moved out of staging
 	- most USB driver moved out of staging
 
 Full details are in the shortlog.
 
 All of these have been in linux-next with no reported issues.  The last
 few changes here were to resolve reported linux-next issues, and they
 seem to have resolved the problems.

6d2b84a4e5 This tree adds the sched_set_fifo*() encapsulation APIs to remove
static priority level knowledge from non-scheduler code.
 
 The three APIs for non-scheduler code to set SCHED_FIFO are:
 
  - sched_set_fifo()
  - sched_set_fifo_low()
  - sched_set_normal()
 
 These are two FIFO priority levels: default (high), and a 'low' priority level,
 plus sched_set_normal() to set the policy back to non-SCHED_FIFO.
 
 Since the changes affect a lot of non-scheduler code, we kept this in a separate
 tree.
 
 When merging to the latest upstream tree there's a conflict in drivers/spi/spi.c,
 which can be resolved via:
 
 	sched_set_fifo(ctlr->kworker_task);

04320b3ef9 media: allegro: fix potential null dereference on header
The pointer header is an alias to msg and msg is being null checked.
However, if msg is null then header is also null and this can lead to
a null pointer dereference on the assignment type = header->type. Fix
this just using header->type after the null check and removing the need
for type as it is only used once.

Addresses-Coverity: ("Dereference before null check")

Pull tasklets API update from Kees Cook:
 "These are the infrastructure updates needed to support converting the
  tasklet API to something more modern (and hopefully for removal
  further down the road).

  There is a 300-patch series waiting in the wings to get set out to
  subsystem maintainers, but these changes need to be present in the
  kernel first. Since this has some treewide changes, I carried this
  series for -next instead of paining Thomas with it in -tip, but it's
  got his Ack.

  This is similar to the timer_struct modernization from a while back,
  but not nearly as messy (I hope). :)
