bfb6cfeeb8 iio: light: vcnl4000: Make irq handling more generic 
This driver supports 4 chips, by which only one (vcnl4010) handles
interrupts and has support for triggered buffer. The setup of these
functions is hardcoded for vcnl4010 inside the generic vcnl4000_probe,
and thus ignores the chip specific configuration structure where all
other chip specific functions are specified.

This complicates adding interrupt handler and triggered buffer support
to chips which may have support for it.

Add members for irq threads and iio_buffer_setup_ops to the generic
vcnl4000_chip_spec struct, so that instead of checking a chip specific
boolean irq support, we check for a chip specific triggered buffer
handler, and/or a chip specific irq thread handler.

0410484273 iio: adc: qcom-spmi-adc5: Suppress probe-deferral error message 
Much like 807efb7102e8 ("thermal: qcom-spmi-adc-tm5: suppress
probe-deferral error message") the ADC5 driver also spams a similar
probe-deferral error on startup when a channel is not yet available:

    [    0.343136] qcom-spmi-adc-tm5 1c40000.spmi:pmic@0:adc-tm@3500: get dt data failed: -517

Suppress it by using dev_err_probe instead, which also takes care of
storing the message as reason for deferring.

The CALIB_FRAC() is defined and might had been used in
tsl2563_calib_from_sysfs(). But let's just move a comment
from it to the latter function.

CLAIB_FRAC_HALF is used in a single place, i.e. in
tsl2563_calib_to_sysfs(). So, let's just inline it there.

While at it, switch to use DIV_ROUND_CLOSEST().
