drm/radeon: warn users when hw_i2c is enabled (v2)
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 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
