[PATCH linux-next] drm/panel: Simplify with dev_err_probe()

From: Yang Guang dev_err_probe() can check if the error code is -EPROBE_DEFER and can return the error code, replacing dev_err() with it simplifies the code. Signed-off-by: Chen Haonan --- drivers/gpu/drm/panel/panel-boe-himax8279d.c | 18 ++ 1 file changed, 6 insertions(+),

[PATCH linux-next] drm/amd/display: use kcalloc instead of open coded arithmetic

From: Yang Guang Dynamic size calculations (especially multiplication) should not be performed in memory allocator (or similar) function arguments due to the risk of them overflowing. This could lead to values wrapping around and a smaller allocation being made than the caller was expecting.
