Please remove the RTS51X_TIP prefix and and and use

#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt

before any #include so that pr_<level> uses
are prefixed in a standard way.

This could be deleted.

alloc OOM messages aren't necessary as there's a generic

This could be on a single line

		pr_warn("Unable to allocate the scsi host\n");
