b43legacy: Fix firmware loading when driver is built into the kernel 2013-01-11T17:18:16+00:00 Larry Finger Larry.Finger@lwfinger.net 2012-12-07T03:55:16+00:00 6a9c6804719aa5c6e17037b947875ed614c2e7b2 commit 576d28a7c73013717311cfcb514dbcae27c82eeb upstream. Recent versions of udev cause synchronous firmware loading from the probe routine to fail because the request to user space times out. The original fix for b43legacy (commit a3ea2c7) moved the firmware load from the probe routine to a work queue, but it still used synchronous firmware loading. This method is OK when b43legacy is built as a module; however, it fails when the driver is compiled into the kernel. This version changes the code to load the initial firmware file using request_firmware_nowait(). A completion event is used to hold the work queue until that file is available. The remaining firmware files are read synchronously. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W.
