[PATCH 5.7 068/112] thermal/drivers/sprd: Fix return value of sprd_thm_probe()

[Greg Kroah-Hartman]

From: Tiezhu Yang <yangtiezhu@xxxxxxxxxxx>

[ Upstream commit b4147917ad4ff2c755e01a7ca296b14030d2d507 ]

When call function devm_platform_ioremap_resource(), we should use IS_ERR()
to check the return value and return PTR_ERR() if failed.
