From 1524bb765d33a5b999b7af361e1e0fc9068b79d5 Mon Sep 17 00:00:00 2001 From: Jacopo Mondi Date: Wed, 16 Jun 2021 14:46:13 +0200 Subject: media: i2c: rdacm20: Embed 'serializer' field There's no reason to allocate dynamically the 'serializer' field in the driver structure. Embed the field and adjust all its users in the driver.
