[ Upstream commit 813cc94c7847ae4a17e9f744fb4dbdf7df6bd732 ]
Smatch reports:
drivers/hwmon/xgene-hwmon.c:757 xgene_hwmon_probe() warn: 'ctx->pcc_comm_addr' from ioremap() not released on line: 757.
This is because in drivers/hwmon/xgene-hwmon.c:701 xgene_hwmon_probe(), ioremap and memremap is not released, which may cause a leak.
To fix this, ioremap and memremap is modified to devm_ioremap and devm_memremap.
