From 1073ab2e9b0d45f318052a3f3690405fc04eda75 Mon Sep 17 00:00:00 2001 From: Michal Kazior Date: Wed, 18 Sep 2013 15:22:17 +0200 Subject: [PATCH] ath10k: fix num_sends_allowed replenishing Commit e9bb0aa39 ("ath10k: delete struct ce_sendlist") broke num_sends_allowed incrementing. num_sends_allowed exceeded initial values and could overflow. This code was supposed to replenish num_sends_allowed for partial sendlist items (i.e. before final sendlist item from a sendlist was completed and could be processed by completion handlers). Fortunately it seems it did not cause any major breakage, yet.
