	[ Upstream commit ee735aa33db16c1fb5ebccbaf84ad38f5583f3cc ] The array contains only 5 elements, but the index calculated by veml6075_read_int_time_index can range from 0 to 7, which could lead to out-of-bounds access. The check prevents this issue. Coverity Issue CID 1574309: (#1 of 1): Out-of-bounds read (OVERRUN) overrun-local: Overrunning array veml6075_it_ms of 5 4-byte elements at element index 7 (byte offset 31) using index int_index (which evaluates to 7) This is hardening against potentially broken hardware. Good to have but not necessary to backport.

2023-12-04	iio: light: add VEML6075 UVA and UVB light sensor driver	Javier Carrasco
	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.
