Thomas Gleixner 862ee699fe USB: sisusbvga: Make console support depend on BROKEN ... The console part of sisusbvga is broken vs. printk(). It uses in_atomic() to detect contexts in which it cannot sleep despite the big fat comment in preempt.h which says: Do not use in_atomic() in driver code. in_atomic() does not work on kernels with CONFIG_PREEMPT_COUNT=n which means that spin/rw_lock held regions are not detected by it. There is no way to make this work by handing context information through to the driver and this only can be solved once the core printk infrastructure supports sleepable console drivers. Make it depend on BROKEN for now.
