Re: [Linux-stable-mirror] [v4] brcmfmac: fix CLM load error for legacy chips when user helper is enabled

For legacy chips without CLM blob files, kernel with user helper function returns -EAGAIN when we request_firmware(), and then driver got failed when bringing up legacy chips. We expect the CLM blob file for legacy chip is not existence in firmware path, but the -ENOENT error is transferred to -EAGAIN in firmware_class.c with user helper. Because of that, we continue with CLM data currently present in firmware if getting error from doing request_firmware().

I'll try to squeeze this to 4.15 still.
