[PATCH 4.18 169/228] ARM: OMAP2+: Fix null hwmod for ti-sysc debug

[Greg Kroah-Hartman]

4.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Tony Lindgren <tony@xxxxxxxxxxx>

[ Upstream commit 4769c003e0fcff0ee001a9102e2605bdaa5880f0 ]

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.
