But really the better fix is to get rid of the status variable completely. Just return directly on the success path. If we were to do that, then both patches would be merged together and called: [patch] Staging: rtl8188eu: fix error handling in rtw_drv_init() But this patch is also acceptable as-is. Thanks for fixing the bug. :) regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
