Wei Chen c22a8d3ae5 fbdev: nvidia: Fix potential divide by zero ... [ Upstream commit 92e2a00f29 ] variable var->pixclock can be set by user. In case it equals to zero, divide by zero would occur in nvidiafb_set_par. Similar crashes have happened in other fbdev drivers. There is no check and modification on var->pixclock along the call chain to nvidia_check_var and nvidiafb_set_par. We believe it could also be triggered in driver nvidia from user site.
