Revert "lib/test_printf.c: call wait_for_random_bytes() before plain %p tests"
This reverts commit ee410f15b1418f2f4428e79980674c979081bcb7. It might prevent the machine from boot. It would wait for enough randomness at the very beginning of kernel_init(). But there is basically nothing running in parallel that would help to produce any randomness. Reported-by: Steven Rostedt (VMware) <rostedt@goodmis.org> Signed-off-by: Petr Mladek <pmladek@suse.com>
