Modifying arguments that are passed into a function is bad
practice, so I'm changing this to strdup the arg thus:
+int lxcContainerSetupHostdevCapsMakePath(const char *dev)
+{
+ int ret = -1;
+ char *dir, *tmp;
+
+ if (VIR_STRDUP(dir, dev) < 0)
+ return -1;
+
+ if ((tmp = strrchr(dir, '/'))) {
+ *tmp = '\0';
+ if (virFileMakePath(dir) < 0) {
+ virReportSystemError(errno,
+ _("Failed to create directory for '%s' dev '%s'"),
+ dir, dev);
+ goto cleanup;
+ }
+ }
+
+ ret = 0;
+
+cleanup:
+ VIR_FREE(dir);
+ return ret;
+}
