Commit 5b779fc introduces the manual release of resources in wacom_remove() as
an addition to the driver's use of devm. The EKR resources can only be
released through wacom_remote_destroy_one() so we skip the manual release for
it.

When snd_seq_pool_done() is called, it marks the closing flag to
refuse the further cell insertions. But snd_seq_pool_done() itself
doesn't clear the cells but just waits until all cells are cleared by
the caller side. That is, it's racy, and this leads to the endless
stall as syzkaller spotted.
This patch addresses the racy by splitting the setup of pool->closing
flag out of snd_seq_pool_done(), and calling it properly before
snd_seq_pool_done().

CONFIG_SND_X86 is a menu config to filter only for x86-specific
drivers in its sub-menu, and this doesn't have to be tristate but
rather it should be a bool. Also, like other sub-menu configs, it's
more user-friendly to be default=y; it's merely a menu config and the

This driver did not set kobj.parent so it likely suffered from
a potential use after free race if the user unregistered the
device while it was in use.
This was not so straightforward a conversion but I think this patch
cleans up its probe's error path significantly.
This patch adds device_initialize, which is required for
cdev_device_add. Then it switches to put_device instead of kfree as
recommended by device_initialize's documentation. This removes a lot
from the error path which was already in __remove.
A couple things needed to be re-ordered to be entirely correct, though.
ida_remove is also moved out of __remove and into unregister to
simplify things and follow the pattern other devices are using.
This also drop an extra unnecessary get_device/put_device in the code.

Mostly straightforward, but we had to remove the rtc_dev_add/del_device
functions as they split up the cdev_add and the device_add.
Doing this also revealed that there was likely another subtle bug:
seeing cdev_add was done after device_register, the cdev probably
was not ready before device_add when the uevent occurs. This would
race with userspace, if it tried to use the device directly after
the uevent. This is fixed just by using the new helper function.
Another weird thing is this driver would, in some error cases, call
cdev_add() without calling cdev_init. This patchset corrects this
by avoiding calling cdev_add if the devt is not set.

This is not as straightforward a conversion as the others
in this series. These drivers did not originally make use of
kobj.parent so they likely suffered from a use after free bug if
someone unregistered the devices while they are being used.
In order to make the conversions, switch from device_register
to device_initialize / cdev_device_add.
In build.c, this patch unwinds a complicated mess of extra
get_device/put_devices and reference tracking by moving device_initialize
early in the attach process. Then it always uses put_device and instead of
using device_unregister and extra get_devices everywhere we just use
cdev_device_del and one put_device once everything is completely done.
This simplifies things dramatically and makes it easier to reason about.
In vmt.c, the patch pushes device initialization up to the beginning of the
device creation and then that function only needs to use put_device
in the error path which simplifies things a good deal.

The use after free is not triggerable here because the cdev holds

module unload, however make the change for consistency.
To make this work the cdev_del needs to move out of the struct device
release function.
This cleans up the error path significantly and thus also fixes a minor
bug where the devnum would not be released if cdev_add failed.

Credit for this patch goes is shared with Dan Williams [1]. I've
taken things one step further to make the helper function more
useful and clean up calling code.
There's a common pattern in the kernel whereby a struct cdev is placed
in a structure along side a struct device which manages the life-cycle
of both. In the naive approach, the reference counting is broken and
the struct device can free everything before the chardev code
is entirely released.
Many developers have solved this problem by linking the internal kobjs
in this fashion:
cdev.kobj.parent = &parent_dev.kobj;
The cdev code explicitly gets and puts a reference to it's kobj parent.
So this seems like it was intended to be used this way. Dmitrty Torokhov
first put this in place in 2012 with this commit:
2f0157f char_dev: pin parent kobject
and the first instance of the fix was then done in the input subsystem
in the following commit:
4a215aa Input: fix use-after-free introduced with dynamic minor changes
Subsequently over the years, however, this issue seems to have tripped
up multiple developers independently. For example, see these commits:
0d5b7da iio: Prevent race between IIO chardev opening and IIO device
(by Lars-Peter Clausen in 2013)
ba0ef85 tpm: Fix initialization of the cdev
(by Jason Gunthorpe in 2015)
5b28dde [media] media: fix use-after-free in cdev_put() when app exits
after driver unbind
(by Shauh Khan in 2016)
This technique is similarly done in at least 15 places within the kernel
and probably should have been done so in another, at least, 5 places.
The kobj line also looks very suspect in that one would not expect
drivers to have to mess with kobject internals in this way.
Even highly experienced kernel developers can be surprised by this
code, as seen in [2].
To help alleviate this situation, and hopefully prevent future
wasted effort on this problem, this patch introduces a helper function
to register a char device along with its parent struct device.
This creates a more regular API for tying a char device to its parent
without the developer having to set members in the underlying kobject.
This patch introduce cdev_device_add and cdev_device_del which
replaces a common pattern including setting the kobj parent, calling
cdev_add and then calling device_add. It also introduces cdev_set_parent
for the few cases that set the kobject parent without using device_add.
