[PATCH 1/4] ARM: OMAP2+: Fix null hwmod for ti-sysc debug
From: tony@atomide.com (Tony Lindgren)

Subsystem:
arm port, omap hwmod support, omap2+ support, the rest · Maintainers:

We may call omap_hwmod_parse_module_range() with no hwmod allocated yet
and may have debug enabled. Let's fix this by checking for hwmod before
trying to use it's name.
