Re: [PATCH 3/6] drm/panic: Fix qr_code, ensure vmargin is positive

Jocelyn Falempe jfalempe@redhat.com writes:

Depending on qr_code size and screen size, the vertical margin can be negative, that means there is not enough room to draw the qr_code.

So abort early, to avoid a segfault by trying to draw at negative coordinates.
