[PATCH RESEND] drm/ast: free correct pointer in astfb_create() error paths

From: Andrew Donnellan
Date: Sun Nov 13 2016 - 22:04:46 EST


In the err_free_vram and err_release_fbi error paths in astfb_create(), we
attempt to free afbdev->sysram. The only jumps to these error paths occur
before we assign afbdev->sysram = sysram. Free sysram instead.
