Subject: [PATCH 1/2] hwspinlock: sprd: fixed warning of unused variable 'sprd_hwspinlock_of_match'

From: Chunyan Zhang <chunyan.zhang@...soc.com>

The macro function of_match_ptr() is NULL if CONFIG_OF is not set, in this
case Clang compiler would complain the of_device_id variable is unused.

Fixes: d8c8bbbb1aba ("hwspinlock: sprd: Add hardware spinlock driver")
