In case of error when writing to userspace, function
mthca_create_cq() do not set an error code before
following its error path.
This patch set error code to -EFAULT when ib_copy_to_udata()
fail.
This was caught when using spatch (aka. coccinelle)
to rewrite call to ib_copy_{from,to}_udata().
Commit af061a644a0e4d4778 add some code in qib_ib_rcv() which
trigger a warning from coccicheck (coccinelle/spatch):

The libcxgb4 package contains a userspace driver for Chelsio T4 and T5
iWARP RNICs. It is a plug-in module for libibverbs that allows programs
to use Chelsio hardware directly from userspace.
A new release is available from:
http://www.openfabrics.org/downloads/cxgb4/libcxgb4-1.3.3.tar.gz
Fixes to enable the negotiation of the supported ird/ord sizes with the

The following series add PCI error handler support for mlx5 driver and
improvements in the mlx5 remove_one function
to make sure that it can execute all the functions to tear down the resources.
IB/mlx5: Implementation of PCI error handler
IB/mlx5: Free resources during PCI error
This patch is to add PCI error handler function support for mlx5.
Created the functions for error_detected and slot_rest, plus will
send a port down event to users when the driver error_detected
function is invoked. This is to prevent a hang seeing in
mcast_remove_one at the time
This patch is to make sure that during a pci error, the remove_one
function frees the resources even though the hardware command failed
to avoid memory leaks when the adapter recovers. Also make sure that
remove_one function goes thru all the functions like disable all irqs
and disable pci so
