Set the timeout value as per cfg80211's set_power_mgmt() request. If the requested value value is left undefined we set it to 2 seconds, the maximum supported value. Signed-off-by: Nicolas Saenz Julienne <redacted> --- Note: I got the 2 seconds value from the Raspberry Pi downstream kernel. .../wireless/broadcom/brcm80211/brcmfmac/cfg80211.c | 10 ++++++++++ 1 file changed, 10 insertions(+)
