From b7e6e9af0d723afdec92364d5e7e064eeef44c8e Mon Sep 17 00:00:00 2001 From: Vidhu Sarwal Date: Wed, 15 Jul 2026 06:45:42 +0530 Subject: [PATCH] iio: light: opt4060: Reject integration times with a non-zero seconds part When setting the integration time, opt4060_write_raw() only uses val2 and ignores val. As a result, a write such as 1.000600 is accepted and programmed as 600 us, silently discarding the whole seconds part. Since all supported integration times are less than one second, any non-zero val represents an invalid input. Reject such values instead of silently accepting them.
