The device tree bindings for lan9662-otp expects the compatible string
to be one of following compatible strings:
microchip,lan9662-otpc
microchip,lan9668-otpc

The problem is that the lan9662-otp driver contains the
microchip,lan9662-otp compatible string instead of
microchip,lan9662-otpc.
Fix this by updating the compatible string in the driver.

Since commit 1da52815 ("binder: fix alloc->vma_vm_mm null-ptr
dereference") binder caches a pointer to the current->mm during open().
This fixes a null-ptr dereference reported by syzkaller. Unfortunately,
it also opens the door for a process to update its mm after the open(),
(e.g. via execve) making the cached alloc->mm pointer invalid.

Things get worse when the process continues to mmap() a vma. From this
point forward, binder will attempt to find this vma using an obsolete
alloc->mm reference. Such as in binder_update_page_range(), where the
wrong vma is obtained via vma_lookup(), yet binder proceeds to happily
insert new pages into it.

To avoid this issue fail the ->mmap() callback if we detect a mismatch
between the vma->vm_mm and the original alloc->mm pointer. This prevents
alloc->vm_addr from getting set, so that any subsequent vma_lookup()
calls fail as expected.

Match the data type of a temporary holding a reference to the FIFO port
with the type of the original reference coming from `struct parport',
avoiding data truncation with LP64 ports such as SPARC64 that refer to
PCI port I/O locations via their corresponding MMIO addresses and will
therefore have non-zero bits in the high 32-bit part of the reference.
And in any case it is cleaner to have the data types matching here.

If device_register() returns error in siox_device_add(),
the name allocated by dev_set_name() need be freed. As
comment of device_register() says, it should use put_device()
to give up the reference in the error path. So fix this
by calling put_device(), then the name can be freed in
kobject_cleanup(), and sdevice is freed in siox_device_release(),
set it to null in error path.

This patch fixes a segfault by adding a null check on synth in
speakup_con_update(). The segfault can be reproduced as follows:

	- Login into a text console

	- Load speakup and speakup_soft modules

	- Remove speakup_soft

	- Switch to a graphics console

This is caused by lack of a null check on `synth` in
speakup_con_update().

Here's the sequence that causes the segfault:

	- When we remove the speakup_soft, synth_release() sets the synth
	  to null.

	- After that, when we change the virtual console to graphics
	  console, vt_notifier_call() is fired, which then calls
	  speakup_con_update().

	- Inside speakup_con_update() there's no null check on synth,
	  so it calls synth_printf().

	- Inside synth_printf(), synth_buffer_add() and synth_start(),
	  both access synth, when it is null and causing a segfault.

Therefore adding a null check on synth solves the issue.

Pull powerpc fixes from Michael Ellerman:

 - Fix a case of rescheduling with user access unlocked, when preempt is
   enabled.

 - A follow-up fix for a recent fix, which could lead to IRQ state
   assertions firing incorrectly.

 - Two fixes for lockdep warnings seen when using kfence with the Hash
   MMU.

 - Two fixes for preempt warnings seen when using the Hash MMU.

 - Two fixes for the VAS coprocessor mechanism used on pseries.

 - Prevent building some of our older KVM backends when
   CONTEXT_TRACKING_USER is enabled, as it's known to cause crashes.

 - A couple of fixes for issues seen with PMU NMIs.

The regulator enables were after the check on the chip variant, which was
very unlikely to return a correct value when not powered.
Presumably all the device anyone is testing on have a regulator that
is already powered up when this code runs for reasons beyond the scope
of this driver. Move the read call down a few lines.

Currently the return value of 'sub_driver->init' is not checked. If
sparse_keymap_setup() called in the init function fails, 'generic_
inputdev' is freed, then it will lead a UAF when using it in generic_
acpi_laptop_init(). Fix it by checking the return value and setting
generic_inputdev to NULL after free, so as to avoid double free it.

The error code in generic_subdriver_init() is always negative, so the
return of generic_subdriver_init() can be simplified.
