Subject: media: i2c: ov8858: Use the v4l2 helper for obtaining the clock
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=5ee9d47242c27f023248870eddcb721eaddfe9e5;p=users%2Fhch%2Fmisc.git

media: i2c: ov8858: Use the v4l2 helper for obtaining the clock

devm_clk_get() fails on ACPI-based platforms, where firmware does not
provide a direct reference to the clock producer.

Replace devm_clk_get() with the new v4l2 helper
devm_v4l2_sensor_clk_get() that works on both DT- and ACPI-based
platforms to retrieve a reference to the clock producer from firmware.
