Jay Buddhabhatti e44eb9d83d drivers: soc: xilinx: check return status of get_api_version() ... commit 9b003e1480 upstream. Currently return status is not getting checked for get_api_version and because of that for x86 arch we are getting below smatch error. CC drivers/soc/xilinx/zynqmp_power.o drivers/soc/xilinx/zynqmp_power.c: In function 'zynqmp_pm_probe': drivers/soc/xilinx/zynqmp_power.c:295:12: warning: 'pm_api_version' is used uninitialized [-Wuninitialized] 295 | if (pm_api_version < ZYNQMP_PM_VERSION) | ^ CHECK drivers/soc/xilinx/zynqmp_power.c drivers/soc/xilinx/zynqmp_power.c:295 zynqmp_pm_probe() error: uninitialized symbol 'pm_api_version'. So, check return status of pm_get_api_version and return error in case of failure to avoid checking uninitialized pm_api_version variable.
