| Subject: nvmem: sprd: Fix return value of sprd_efuse_probe() |
| |
| From: Tiezhu Yang <yangtiezhu@loongson.cn> |
| |
| [ Upstream commit bcd14bb7a68520bf88e45e91d354e43535624f82 ] |
| |
| When call function devm_platform_ioremap_resource(), we should use IS_ERR() |
| to check the return value and return PTR_ERR() if failed. |
