These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.
While add it, also remove commas after the sentinel entries.

Add support for a new SPMI vibrator module which is very similar
to the vibrator module inside PM8916 but has a finer drive voltage
step and different output voltage range, its drive level control
is expanded across 2 registers. The vibrator module can be found
in following Qualcomm PMICs: PMI632, PM7250B, PM7325B, PM7550BA.

Currently, vibrator control register addresses are hard coded,
including the base address and offsets, it's not flexible to
support new SPMI vibrator module which is usually included in
different PMICs with different base address. Refactor it by using

The output voltage is inclusive hence the max level calculation is

"This contains a bunch of cleanups and simplifications across the

Perhaps the most notable change here is the addition of an API that
allows PWMs to be used in atomic contexts, which is useful when time-

signals.
Finally, I have decided to step down as PWM subsystem maintainer. Due
to other responsibilities I have lately not been able to find the time

for the past few years and has many things planned for the future, has

This patch adds support for each available OTP variant of the device.
The OTP configuration cannot be read over I2C, so it is derived from
a compatible string instead.
Early revisions of the D0 order code require their OTP-enabled func-
tionality to be manually restored following a soft reset; this patch
accommodates this erratum as well.

This patch adds support for slider gestures that can be expressed
by the device. Each gesture (e.g. tap or hold) can be mapped to a
unique keycode for either slider 0 or 1.
With this change, raw slider coordinates are reported only if the
slider has no keycodes defined. This prevents unwanted mouse cur-
sor movement when expressing axial gestures (e.g. swipe) and also
eliminates some unnecessary I2C traffic.
Different revisions of silicon use different tap and swipe timeout
step sizes. Apply an appropriate scaling factor depending on which
revision is found.
To facilitate this change, store the iqs269_ver_info struct in the
driver's private data so that other functions can use it after the
driver has probed.
Last but not least, a former reserved field in iqs269_ver_info now
contains useful information; give it a name (fw_num).

This add a mapping for the airplane mode button on the TUXEDO Pulse Gen3.
While it is physically a key it behaves more like a switch, sending a key
down on first press and a key up on 2nd press. Therefor the switch event
is used here. Besides this behaviour it uses the HID usage-id 0xc6
(Wireless Radio Button) and not 0xc8 (Wireless Radio Slider Switch), but
since neither 0xc6 nor 0xc8 are currently implemented at all in
soc_button_array this not to standard behaviour is not put behind a quirk
for the moment.

In order to introduce a pwm api which can be used from atomic context,
we will need two functions for applying pwm changes:
int pwm_apply_might_sleep(struct pwm *, struct pwm_state *);
int pwm_apply_atomic(struct pwm *, struct pwm_state *);
This commit just deals with renaming pwm_apply_state(), a following
commit will introduce the pwm_apply_atomic() function.

similar things where the new entry goes _after_ the termination without
the compiler noticing.
* Move OF table near to the user.

Add the needed device-tree compatible strings to the MAX77693 haptic
driver, so it can be automatically loaded when compiled as a kernel
module and given device-tree contains separate (i.e. 'motor-driver') node
under the main PMIC node. When device is instantiated from device-tree,
the driver data cannot be read via platform_get_device_id(), so get
device type from the parent MFD device instead, what works for both
cases.

syzbot has found a use-after-free bug [1] in the powermate driver. This
happens when the device is disconnected, which leads to a memory free from
the powermate_device struct. When an asynchronous control message
completes after the kfree and its callback is invoked, the lock does not
exist anymore and hence the bug.
Use usb_kill_urb() on pm->config to cancel any in-progress requests upon
device disconnection.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Instead of creating driver-specific device attributes with
devm_device_add_group() have device core do this by setting up dev_groups
pointer in the driver structure.
