+Subject: drm/radeon: warn users when hw_i2c is enabled (v2)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8

+From: Alex Deucher <alexander.deucher@amd.com>
+
+commit d195178297de9a91246519dbfa98952b70f9a9b6 upstream.
+
+The hw i2c engines are disabled by default as the
+current implementation is still experimental. Print
+a warning when users enable it so that it's obvious
+when the option is enabled.
+
+v2: check for non-0 rather than 1
