Subject: [PATCH 144/277] brcmfmac: Delete redundant length check
|
|
|
|
brcmf_fweh_process_event() sets event->datalen to the
|
|
endian-swapped value of event_packet->msg.datalen, which is the
|
|
same as emsg.datalen. This length is already validated in
|
|
brcmf_fweh_process_event(), so there is no need to check it
|
|
again upon dequeuing the event.
|
|
