[PATCH AUTOSEL 5.4 38/63] gpio: zynq: Check return value of pm_runtime_get_sync

[Sasha Levin]

From: Srinivas Neeli <srinivas.neeli@xxxxxxxxxx>

[ Upstream commit a51b2fb94b04ab71e53a71b9fad03fa826941254 ]

Return value of "pm_runtime_get_sync" API was neither captured nor checked.
Fixed it by capturing the return value and then checking for any warning.

Addresses-Coverity: "check_return"
