Hi, thanks for your patch. > [PATCH] Subject: fbdev: sstfb: Make CONFIG_FB_DEVICE optional 'Subject:' should not be part of the subject line. Is that an issue with your mail setup?

You should mention that the sysfs setting only controls VGA pass-through state and is not required for the display to work correctly.

Here and below. The patch should be good with the suggested changes. Please send an update.

The sstfb driver currently depends on CONFIG_FB_DEVICE to create sysfs entries and access info->dev. This patch wraps the relevant code blocks with #ifdef CONFIG_FB_DEVICE, allowing the driver to be built and used even if CONFIG_FB_DEVICE is not selected. Tested by building with and without CONFIG_FB_DEVICE, both of which compile without issues Signed-off-by: Gonzalo Silvalde Blanco <gonzalo.silvalde@gmail.com> --- drivers/video/fbdev/sstfb.c | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-)
