Since the Armbian sources refer to linux 4.19.76 as being linux-mainline, all the patches from linux-4.19 were moved to linux-mainline_4.19 and the linux_4.19.76 recipes was named accordingly. This patch makes 4.19.76 as default version for linux Signed-off-by: Vicentiu Galanopulo <vicentiu@balena.io>

Subject: [PATCH 090/146] drm/sun4i: tcon: prevent tcon->panel dereference if
|
|
null
|
|
|
|
If using tcon with VGA, tcon->panel will be null(0), this will cause
|
|
segmentation fault when trying to dereference tcon->panel->connector.
|
|
|
|
Add tcon->panel null check before calling
|
|
sun4i_tcon0_mode_set_dithering().
