[PATCH] spi: fix for_each_child.cocci warnings

[kernel test robot]

From: kernel test robot <lkp@intel.com>

drivers/spi/spi-zynqmp-gqspi.c:1360:1-33: WARNING: Function "for_each_available_child_of_node" should have of_node_put() before break around line 1365.
drivers/spi/spi-zynqmp-gqspi.c:1372:1-33: WARNING: Function "for_each_available_child_of_node" should have of_node_put() before break around line 1377.


Semantic patch information:
 False positives can be due to function calls within the for_each
 loop that may encapsulate an of_node_put.
