From 782203884eea5f610444bcf4ed1b4af0010911eb Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Wed, 16 Apr 2008 21:09:25 -0700 Subject: IB/ipath: Fix PCI config write size used to clear linkctrl error bits In slave_or_pri_blk(), pci_write_config_byte() is used to write a 16-bit quantity to clear linkctrl CRC error bits. This is clearly a bug and also causes the warning drivers/infiniband/hw/ipath/ipath_iba6110.c: In function 'slave_or_pri_blk': drivers/infiniband/hw/ipath/ipath_iba6110.c:849: warning: overflow in implicit constant conversion Fix this by using pci_write_config_word() instead.
