Return a negative error code on failure. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ identifier ret; expression e1,e2; @@ ( if (\(ret < 0\|ret != 0\)) { ... return ret; } | ret = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> This patch also changes the subsequent dev_err call to use err rather than recomputing PTR_ERR(hba->devfreq). The format of the error value is changed from %ld to %d to reflect the type or err.
