The driver neglects to check the result of platform_get_irq()'s call and
blithely passes the negative error codes to request_threaded_irq() (which
takes *unsigned* IRQ #), causing it to fail with -EINVAL, overriding an
original error code. Stop calling request_threaded_irq() with the invalid
IRQ #s.

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.

while with no reported issues:
- extcon driver updates
- habannalab driver updates
- mei driver updates
- uio driver updates
- binder fixes and features added
- soundwire driver updates
- mhi bus driver updates
- phy driver updates
- coresight driver updates
- fpga driver updates
- speakup driver updates
- slimbus driver updates
- various small char and misc driver updates"
