Subject[PATCH v6 07/10] clocksource: timer-dm: Hook device platform data if not already assigned
Date
From: Ladislav Michl <ladis@linux-mips.org>

In the case of device tree boot the device platform data is usually
NULL so hook the platform data obtained from the match.
As part of un-constify the platform_data pointer.
