From 351434c6ba92e1fe7799a0c33c1412584a0fb3de Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Tue, 15 Dec 2015 13:52:36 +0300 Subject: [PATCH] qlge: fix a timeout loop in ql_change_rx_buffers() The problem here is that after the loop we test for "if (!i) " but because "i--" is a post-op we exit with i set to -1. I have fixed this by changing it to a pre-op instead. I had to change the starting value from 3 to 4 so that we still iterate 3 times. Signed-off-by: Dan Carpenter Signed-off-by: David S.
