wusb: use printk_ratelimited() instead of printk_ratelimit()

2011-07-01T21:43:25+00:00

Since printk_ratelimit() shouldn't be used anymore (see comment in
include/linux/printk.h), replace it with printk_ratelimited()

USB: wusbcore: return negative error codes

2011-06-07T16:09:10+00:00

cbaf_cdid_get() is only used in cbaf_wusb_chid_store().

In the original code cbaf_cdid_get() returns either a negative error
code or a small positive value on error.  I have changed it to
return -ENOENT if there is not enough data available.

In the original code the caller changed the negative error codes to
positive return values.  I've changed it to just return the error
value directly.

USB 3.0 Hub Changes

2011-03-14T01:07:11+00:00

Update the USB core to deal with USB 3.0 hubs.  These hubs have a slightly
different hub descriptor than USB 2.0 hubs, with a fixed (rather than
variable length) size.  Change the USB core's hub descriptor to have a
union for the last fields that differ.  Change the host controller drivers
that access those last fields (DeviceRemovable and PortPowerCtrlMask) to
use the union.

Translate the new version of the hub port status field into the old
version that khubd understands.  (Note: we need to fix it to translate the
roothub's port status once we stop converting it to USB 2.0 hub status
internally.)

Add new code to handle link state change status.  Send out new control
messages that are needed for USB 3.0 hubs, like Set Hub Depth.

This patch is a modified version of the original patch submitted by John
Youn.  It's updated to reflect the removal of the "bitmap" #define, and
change the hub descriptor accesses of a couple new host controller
drivers.

USB: Remove bitmap #define from hcd.h

2011-03-14T01:07:07+00:00

Using a #define to redefine a common variable name is a bad thing,
especially when the #define is in a header.  include/linux/usb/hcd.h
redefined bitmap to DeviceRemovable to avoid typing a long field in the
hub descriptor.  This has unintended side effects for files like
drivers/usb/core/devio.c that include that file, since another header
included after hcd.h has different variables named bitmap.

Remove the bitmap #define and replace instances of it in the host
controller code.  Cleanup the spaces around function calls and square
brackets while we're at it.

wusb: fix find_first_zero_bit() return value check

2011-03-03T00:52:28+00:00

In wusb_cluster_id_get(), if no zero bits exist in wusb_cluster_id_table,
find_first_zero_bit() returns CLUSTER_IDS.

But it is impossible to detect that the bitmap is full because there
is an off-by-one error in the return value check.  It will cause
unexpected memory access by setting bit out of wusb_cluster_id_table
bitmap, and caller will get wrong cluster id.
