From: Pan Bian <bianpan2...@163.com> In function hfc4s8s_probe(), the value of return variable err should be negative on failures. However, when the call to request_region() returns NULL, the value of err is 0. This patch fixes the bug, assiging "-ENOMEM" to err on the path that request_region() fails.
