From: "Luis R. Rodriguez" <mcgrof@suse.com>
cxgb4 uses request_firmware() 3 times, one for firmware, one for optional configuration files and another for ethtools flash. Since the configuration update is optional on devices that don't have a configuration file update it means we'd wait unnecessarily for the extra udev timeout, which by default is 60 seconds. Avoid this extra delay.
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); ... }
