From ab1dd9963137a1e122004d5378a581bf16ae9bc8 Mon Sep 17 00:00:00 2001 From: Malcolm Priestley Date: Sun, 7 Oct 2012 08:27:00 +0100 Subject: [PATCH] staging: vt6656: [BUG] out of bound array reference in RFbSetPower. Calling RFbSetPower with uCH zero value will cause out of bound array reference. This causes 64 bit kernels to oops on boot. Note: Driver does not function on 64 bit kernels and should be blacklisted on them.
