Subject: [DCCP] ccid3: return value in ccid3_hc_rx_calc_first_li
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=832e3ca62d6ee1893db05f5202c24ae5331e19ba;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

[DCCP] ccid3: return value in ccid3_hc_rx_calc_first_li

In a recent patch we introduced invalid return codes which will result in the
opposite of what is intended (i.e. send more packets in face of peculiar
network conditions).

This fixes it by returning ~0 which means not calculated as per
dccp_li_hist_calc_i_mean.
