From: "Luis R. Rodriguez" <mcg...@suse.com>
vub300 uses the request_firmware() API for downloading
pseudo code twice and if this fails its not considered fatal.
Avoid letting the request linger 60 seconds because of udev if
one of the requests fails by explicitly skipping the udev helper.
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);
...
}
