Convert a nonnegative error return code to a negative one, as returned
elsewhere in the function.A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)//
(
if@p1 (\(ret < 0\|ret != 0\))
{ ... return ret; }
|
ret@p1 = 0
)
... when != ret = e1
when != &ret
*if(...)
{
... when != ret = e2
when forall
return ret;
}

Modify RapidIO mport device name assignment to include device name of PCIe
side of Tsi721 bridge. The new name format is intended to provide
definitive reference between RapidIO and PCIe sides of the bridge in
systems with multiple Tsi721 bridges.Signed-off-by: Alexandre Bounine

Make sure that there is no doorbell messages left behind due to disabled
interrupts during inbound doorbell processing.The most common case for this bug is loss of rionet JOIN messages in
systems with three or more rionet participants and MSI or MSI-X enabled.
As result, requests for packet transfers may finish with "destination
unreachable" error message.This patch is applicable to kernel versions starting from v3.2.

Fix indexed register offset definitions that use decimal (wrong) instead
of hexadecimal (correct) notation for indexing multipliers.Incorrect definitions do not affect Tsi721 driver in its current default
configuration because it uses only IDB queue 0. Loss of inbound
doorbell functionality should be observed if queue other than 0 is used.Signed-off-by: Alexandre Bounine

Fix a bug that causes a kernel panic when the number of received doorbells
is larger than number of entries in the inbound doorbell queue (current
default value = 512).Another possible indication for this bug is large number of spurious
doorbells reported by tsi721 driver after reaching the queue size maximum.Signed-off-by: Alexandre Bounine

aborts during intensive traffic.
- replace hardcoded offset of PCIe capability block by making it use the
common function.This patch is applicable to kernel versions starting from 3.2-rc1.

Bug fix for Tsi721 RapidIO mport driver: Tsi721 supports four RapidIO

resources has to be properly reported to allow use of all available

Add RapidIO mport driver for IDT TSI721 PCI Express-to-SRIO bridge device.
The driver provides full set of callback functions defined for mport
devices in RapidIO subsystem. It also is compatible with current version
of RIONET driver (Ethernet over RapidIO messaging services).This patch is applicable to kernel versions starting from 2.6.39.
