Kulikov, can you at least build test your patches? Casts are not always incorrect, particularly when private cookies are "unsigned long" as is the case here: drivers/char/hw_random/n2-drv.c: In function ¡n2rng_data_read¢: drivers/char/hw_random/n2-drv.c:390: warning: initialization makes pointer from integer without a cast Herbert, please revert this change, thanks. And I suspect there might be more of these hwrng driver duds that went into the tree, it's worth checking out. :-) Thanks. commit 8b9cfdca9c52f7d39c3ccfac1668e31c20c9f42e Author: Kulikov Vasiliy Date: Mon Jul 5 21:25:06 2010 +0800 hwrng: n2-drv - remove casts from void* Remove unnesessary casts from void*.
