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 Reviewed-by: Christian König Signed-off-by: Ben Hutchings --- diff --git a/drivers/gpu/drm/radeon/radeon_i2c.c b/drivers/gpu/drm/radeon/radeon_i2c.c index cf203510b16b..894b5f0fb08c 100644 --- a/drivers/gpu/drm/radeon/radeon_i2c.c +++ b/drivers/gpu/drm/radeon/radeon_i2c.c @@ -998,6 +998,9 @@ void radeon_i2c_destroy(struct radeon_i2c_chan *i2c) /* Add the default buses */ void radeon_i2c_init(struct radeon_device *rdev) { + if (radeon_hw_i2c) + DRM_INFO("hw_i2c forced on, you may experience display detection problems!\n"); + if (rdev->is_atom_bios) radeon_atombios_i2c_init(rdev); else
