Miller" <davem@...emloft.net>, Jérôme Pouiller <Jerome.Pouiller@...abs.com> Subject: [PATCH v2 37/65] staging: wfx: simplify wfx_set_mcast_filter() From: Jérôme Pouiller <jerome.pouiller@...abs.com> HIF functions return only serious errors (OOM or device freeze). The current handling of errors in wfx_set_mcast_filter() does not bring anything. Finally it may disturb the developer more than it helps.
