[PATCH v2 0/2] iio: light: vcnl4000: support shared IRQs

[Tsz Shan Chan]

This series contains two changes for the vcnl4000 driver.

Patch 1 makes .num_channels match .channels for vcnl4200. vcnl4040 and
vcnl4000 channel arrays have the same size, so no functional change.

Patch 2 adds shared IRQ support. It changes the trigger type from
falling edge to low level and adds IRQF_SHARED. The IRQ handlers return
IRQ_NONE when the device did not generate the interrupt.
