There is no need to store the result of the & operation back to the
variable var. The store is redundant, replace &= with just &.
Cleans up clang scan warning:

Pull char / misc / other smaller driver subsystem updates from Greg KH:
"Here is the large set of char, misc, and other driver subsystem
updates for 5.19-rc1. The merge request for this has been delayed as I
wanted to get lots of linux-next testing due to some late arrivals of
changes for the habannalabs driver.
Highlights of this merge are:
- habanalabs driver updates for new hardware types and fixes and
other updates
- IIO driver tree merge which includes loads of new IIO drivers and
cleanups and additions
- PHY driver tree merge with new drivers and small updates to
existing ones
- interconnect driver tree merge with fixes and updates
- soundwire driver tree merge with some small fixes
- coresight driver tree merge with small fixes and updates
- mhi bus driver tree merge with lots of updates and new device
support
- firmware driver updates
- fpga driver updates
- lkdtm driver updates (with a merge conflict, more on that below)
- extcon driver tree merge with small updates
- lots of other tiny driver updates and fixes and cleanups, full
details in the shortlog.
All of these have been in linux-next for almost 2 weeks with no
reported problems"

Pull ARMv4T/v5 multiplatform support from Arnd Bergmann:
"This series has been 12 years in the making, it mostly finishes the
work that was started with the founding of Linaro to clean up platform
support in the kernel.
The largest change here is a cleanup of the omap1 platform, which is
the final ARM machine type to get converted to the common-clk
subsystem. All the omap1 specific drivers are now made independent of
the mach/*.h headers to allow the platform to be part of a generic
ARMv4/v5 multiplatform kernel.
The last bit that enables this support is still missing here while we
wait for some last dependencies to make it into the mainline kernel
through other subsystems.
The s3c24xx, ixp4xx, iop32x, ep93xx and dove platforms were all almost
at the point of allowing multiplatform kernels, this work gets
completed here along with a few additional cleanup. At the same time,
the s3c24xx and s3c64xx are now deprecated and expected to get removed
in the future.
The PXA and OMAP1 bits are in a separate branch because of
dependencies. Once both branches are merged, only the three Intel
StrongARM platforms (RiscPC, Footbridge/NetWinder and StrongARM1100)
need separate kernels, and there are no plans to include these"

The extcon_get_extcon_dev() function returns error pointers on error,
NULL when it's a -EPROBE_DEFER defer situation, and ERR_PTR(-ENODEV)
when the CONFIG_EXTCON option is disabled. This is very complicated for
the callers to handle and a number of them had bugs that would lead to
an Oops.
In real life, there are two things which prevented crashes. First,
error pointers would only be returned if there was bug in the caller
where they passed a NULL "extcon_name" and none of them do that.
Second, only two out of the eight drivers will build when CONFIG_EXTCON
is disabled.
The normal way to write this would be to return -EPROBE_DEFER directly
when appropriate and return NULL when CONFIG_EXTCON is disabled. Then
the error handling is simple and just looks like:
dev->edev = extcon_get_extcon_dev(acpi_dev_name(adev));
if (IS_ERR(dev->edev))
return PTR_ERR(dev->edev);
For the two drivers which can build with CONFIG_EXTCON disabled, then
extcon_get_extcon_dev() will now return NULL which is not treated as an
error and the probe will continue successfully. Those two drivers are
"typec_fusb302" and "max8997-battery". In the original code, the
typec_fusb302 driver had an 800ms hang in tcpm_get_current_limit() but
now that function is a no-op. For the max8997-battery driver everything
should continue working as is.

When the dwc2 platform device is removed, it unregisters the generic
phy. usb_remove_phy() is called and the dwc2 usb_phy is removed from the
"phy_list", but the uevent may still attempt to get the usb_phy from the
list, resulting in a page fault bug. Currently we can't access the usb_phy
from the "phy_list" after the device is removed. As a fix check to make
sure that we can get the usb_phy before moving forward with the uevent.

The B_SESS_VLD_WAKEUP_EN bit 6 was added by a mistake in a previous
commit. This bit corresponds to B_SESS_END_WAKEUP_EN, which we don't use.
The B_VBUS_VLD_WAKEUP_EN doesn't exist at all and B_SESS_VLD_WAKEUP_EN
needs to be in place of it. We don't utilize B-sensors in the driver,
so it never was a problem, nevertheless let's correct the definition of
the bits.

Some devices need an extra delay after losing VBUS, otherwise VBUS may
be detected as active at suspend time, preventing the PHY's suspension
by the VBUS detection sensor. This problem was found on Asus Transformer
TF700T (Tegra30) tablet device, where the USB PHY wakes up immediately
from suspend because VBUS sensor continues to detect VBUS as active after
disconnection. We need to poll the PHY's VBUS wakeup status until it's
deasserted before suspending PHY in order to fix this minor trouble.

The USB charger type and status was already propagated to userspace
through kobject_uevent_env during charger notify work. Nevertheless the
uevent could be lost e.g. because it could be fired at an early kernel
boot stage, way before udev daemon or any other user-space app was able
to catch it. Registering uevent hook for introduced usb_phy_dev_type
will allow to query sysfs 'uevent' file to restore that information at
any time.

The PHY hardware needs the delay of 2ms after power up, otherwise initial
interrupt may be lost if USB controller is accessed before PHY is settled
down. Previously this issue was masked by implicit delays, but now it pops
up after squashing the older ehci-tegra driver into the ChipIdea driver.

No idea why this driver is using a char device node, statically
allocated, with no dynamic allocation or hook up with devtmpfs, along
with a reserverd major number, for "special" operations, not all of
which ever were implemented.
So just rip it out, as no one must be using it because no modern system
will ever actually create the /dev/ node it needs.

This file has a HUGE debugging sysfs file that spews out a lot of
information all at once, which violates the one-value-per-file rule for
sysfs. If this is really needed, it should go into debugfs, but given
the age of this driver, I strongly doubt anyone is using it anymore.
So just remove the file entirely, it was never documented, so obviously,
no one actually needed it :)

A call to 'regulator_get()' is hidden in 'twl6030_usb_ldo_init()'. A
corresponding put must be performed in the error handling path, as
already done in the remove function.
While at it, also move a 'free_irq()' call in the error handling path in

Tools like Coccinelle may erroneously recommend to use the
devm_platform_ioremap_resource() API for the registers mapping because
these tools are not aware about the implementation details of the driver.
Let's add a clarifying comments to the code, which should help to stop
future attempts to break the driver.
