From aea570ea6bc6532cc33a2fb98d3a7348781f3b76 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Tue, 7 Jan 2014 10:05:02 -0500 Subject: drm/radeon: warn users when hw_i2c is enabled (v2) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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 Reviewed-by: Christian König Signed-off-by: Greg Kroah-Hartman --- drivers/gpu/drm/radeon/radeon_i2c.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/drivers/gpu/drm/radeon/radeon_i2c.c b/drivers/gpu/drm/radeon/radeon_i2c.c index 6076e85aa5da..19d68c55c7e6 100644 --- a/drivers/gpu/drm/radeon/radeon_i2c.c +++ b/drivers/gpu/drm/radeon/radeon_i2c.c @@ -1020,6 +1020,9 @@ 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 -- cgit v1.2.3
