Gr{oetje,eeting}s,
. the real danger is the
strcat(msg, str);
on the next line.
Fortunately this whole debug printing block (including the strcpy)
can (and should) be rewritten to just use "%*ph".

Indeed, on 32-bit size_t is "unsigned int", not "unsigned long".

Sig
ridge_init':
kmb_dsi.c:(.text+0xb14): undefined reference to `mipi_dsi_host_register'
Fix this be selecting DRM_MIPI_DSI, like other drivers do.

drivers/gpu
are only
supported in arm64 kernel builds,
2. The dependencies on OF and COMMON_CLK can be dropped for
compile-testing, as the driver builds fine regardless.

Hi Daniel,
Replying "early" (see below), as this was applied to

s rendered correctly, but "L"
turns into "Γ" (Greek Gamma).
I suspect something went wrong with the display initialization
sequence.

So support for images with offsets or widths that are not a multiple
of 8 got broken in cfb_imageblit(). Oops...
BTW, the various drawing routine
ored display on my Adafruit
FeatherWing 128x32 OLED.
