The Vishay VEMl6075 is a low power, 16-bit resolution UVA and UVB
light sensor with I2C interface and noise compensation (visible and
infrarred).
Every UV channel generates an output signal measured in counts per
integration period, where the integration time is configurable.
This driver adds support for both UV channels and the ultraviolet
index (UVI) inferred from them according to the device application note
with open-air (no teflon) coefficients.

instead of a single tab for all the entries in that MAINTAINERS section.
Although, the get_maintainer.pl script handles spaces instead of tabs
silently, the MAINTAINERS will quickly get into a messy state with

hardwired for and the gpio-modes property is not allowed.
This adds support for the case where the mode pins are hardwired for

from the config register.
The case of hardwired position or velocity mode is not supported as
there would be no way to configure the device.

iio: adc: Add driver support for MAX34408/9
The MAX34408/MAX34409 are two- and four-channel current monitors that are
configured and monitored with a standard I2C/SMBus serial interface. Each
unidirectional current sensor offers precision high-side operation with a
low full-scale sense voltage. The devices automatically sequence through
two or four channels and collect the current-sense samples and average them
to reduce the effect of impulse noise. The raw ADC samples are compared to
user-programmable digital thresholds to indicate overcurrent conditions.
Overcurrent conditions trigger a hardware output to provide an immediate
indication to shut down any necessary external circuitry.
Add as ADC driver which only supports current monitoring for now.

spi: Fix null dereference on suspend
A race condition exists where a synchronous (noqueue) transfer can be
active during a system suspend. This can cause a null pointer
dereference exception to occur when the system resumes.
Example order of events leading to the exception:
1. spi_sync() calls __spi_transfer_message_noqueue() which sets
ctlr->cur_msg
2. Spi transfer begins via spi_transfer_one_message()
3. System is suspended interrupting the transfer context
4. System is resumed
6. spi_controller_resume() calls spi_start_queue() which resets cur_msg
to NULL
7. Spi transfer context resumes and spi_finalize_current_message() is
called which dereferences cur_msg (which is now NULL)
Wait for synchronous transfers to complete before suspending by
acquiring the bus mutex and setting/checking a suspend flag.

pwm: Fix double shift bug
These enums are passed to set/test_bit(). The set/test_bit() functions
take a bit number instead of a shifted value. Passing a shifted value
is a double shift bug like doing BIT(BIT(1)). The double shift bug
doesn't cause a problem here because we are only checking 0 and 1 but
if the value was 5 or above then it can lead to a buffer overflow.

pwm: samsung: Fix a bit test in pwm_samsung_resume()
The PWMF_REQUESTED enum is supposed to be used with test_bit() and not
used as in a bitwise AND. In this specific code the flag will never be
set so the function is effectively a no-op.

fbdev: amifb: Convert to platform remove callback returning void
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.

smb3: allow dumping session and tcon id to improve stats analysis and debugging
When multiple mounts are to the same share from the same client it was not
possible to determine which section of /proc/fs/cifs/Stats (and DebugData)
correspond to that mount. In some recent examples this turned out to be
a significant problem when trying to analyze performance data - since
there are many cases where unless we know the tree id and session id we
can't figure out which stats (e.g. number of SMB3.1.1 requests by type,
the total time they take, which is slowest, how many fail etc.) apply to
which mount. The only existing loosely related ioctl CIFS_IOC_GET_MNT_INFO
does not return the information needed to uniquely identify which tcon
is which mount although it does return various flags and device info.
Add a cifs.ko ioctl CIFS_IOC_GET_TCON_INFO (0x800ccf0c) to return tid,
session id, tree connect count.
