Subject: [PATCH 1/1] ipu3-cio2: Build bridge only if ACPI is enabled

From: Sakari Ailus <[email-masked]>
Date: Tue, 2 Feb 2021 22:14:40 +0200

ipu3-cio2-bridge uses several features of the ACPI framework that have no
meaningful replacement when ACPI is disabled. Instead of adding #ifdefs to
the affected places, only build the bridge code if CONFIG_ACPI is enabled.

Fixes: 803abec64ef9 ("media: ipu3-cio2: Add cio2-bridge to ipu3-cio2 driver")
