[for-next][PATCH 1/3] tracing/mmiotrace: Use trace_assign_type() in mmio_print_mark()

[Steven Rostedt <rostedt@kernel.org>]

From: "Masami Hiramatsu (Google)" <mhiramat@kernel.org>

In mmio_print_mark(), a raw C cast (struct print_entry *)entry is used to
obtain the print_entry pointer.

Use the standard trace_assign_type() macro instead, matching the usage in
mmio_print_rw() and mmio_print_map().
