From 9d00ccabfbb522bb7a23ed329be2bf6aee04fe06 Mon Sep 17 00:00:00 2001 From: Ondrej Jirman Date: Sat, 17 Feb 2024 19:49:11 +0100 Subject: media: i2c: dw9714: Fix occasional probe errors The powerup delay was not observed during probe, leading to occasional I2C communication failures in RPM suspend callback. Power delay is properly observed in resume callback already.
