| Subject: crypto: s5p-sss - Add error handling in s5p_aes_probe() |
| |
| From: Tang Bin <tangbin@cmss.chinamobile.com> |
| |
| commit a472cc0dde3eb057db71c80f102556eeced03805 upstream. |
| |
| The function s5p_aes_probe() does not perform sufficient error |
| checking after executing platform_get_resource(), thus fix it. |
| |
| Fixes: c2afad6c6105 ("crypto: s5p-sss - Add HASH support for Exynos") |
