This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

steelseries_srws1_probe() still does not use devm_kzalloc() and
devm_led_classdev_register(), so there is a lot of code to safely manage
heap, which reduces readability and may cause memory leaks due to minor
patch mistakes in the future.
Therefore, it should be changed to use devm_kzalloc() and
devm_led_classdev_register() to easily and safely manage heap.
Also, the current steelseries driver mainly checks sd->quriks to determine
which product a specific HID device is, which is not the correct way.
remove(), unlike probe(), does not receive struct hid_device_id as an
argument, so it must check hdev unconditionally to know which product
it is.
However, since struct steelseries_device and struct steelseries_srws1_data
have different structures, if SRWS1 is removed in remove(), converts
hdev->dev, which is initialized to struct steelseries_srws1_data,
to struct steelseries_device and uses it. This causes various
memory-related bugs as completely unexpected values exist in member
variables of the structure.
Therefore, in order to modify probe() and remove() to work properly,
Arctis 1, 9 should be added to HID_USB_DEVICE and some functions should be
modified to check hdev->product when determining HID device product.

In certain circumstances, such as when creating I2C-connected HID
devices, we want to pass and retain some quirks (axis inversion, etc).
The source of such quirks may be device tree, or DMI data, or something
else not readily available to the HID core itself and therefore cannot
be reconstructed easily. To allow this, introduce "initial_quirks" field
in hid_device structure and use it when determining the final set of
quirks.
This fixes the problem with i2c-hid setting up device-tree sourced
quirks too late and losing them on device rebind, and also allows to
sever the tie between hid-code and i2c-hid when applying DMI-based
quirks.
