Cengiz Can fcdb84cc5b kdb: remove unnecessary null check of dbg_io_ops ... `kdb_msg_write` operates on a global `struct kgdb_io *` called `dbg_io_ops`. It's initialized in `debug_core.c` and checked throughout the debug flow. There's a null check in `kdb_msg_write` which triggers static analyzers and gives the (almost entirely wrong) impression that it can be null. Coverity scanner caught this as CID 1465042. I have removed the unnecessary null check and eliminated false-positive forward null dereference warning.
