From 80140b71e0bd2d9f6762791567cfd0aa04f20419 Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Tue, 24 Jun 2014 15:39:43 -0700 Subject: [PATCH] p54: use request_firmware_direct() for optional EEPROM override The p54 driver uses request_firmware() twice, once for actual firmware and then another time for an optional user overide on EEPROM, 3826.eeprom. The custom EEPROM is optional but if not present we'll introduce an extra lag of 60 seconds with udev present. Annotate we don't want udev nonsense here to avoid the lag in case its not present. This was found with the following SmPL patch. @ firmware_not_critical @ expression cf; expression config_file; expression dev; int ret; identifier l; statement S; @@ - ret = request_firmware(&cf, config_file, dev); + ret = request_firmware_direct(&cf, config_file, dev); if (ret < 0) { ... when != goto l; when != return ret; when any } else { ... release_firmware(cf); ... } Cc: Takashi Iwai Cc: Christian Lamparter Cc: linux-wireless@vger.kernel.org Cc: cocci@systeme.lip6.fr Signed-off-by: Luis R.
