[PATCH v1 20/55] media: i2c: max2175: Use the v4l2 helper for obtaining the clock
Posted by Mehdi Djait 3 months, 3 weeks ago
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.
