Thip patchset avoids accessing auto-suspended device in ioctl path,
which is generally triggered by some network utility(ethtool, ifconfig,
...)

Most of network devices have the problem, but as discussed in the
thread:

        http://marc.info/?t=135054860600003&r=1&w=2

the problem should be solved inside driver.

Considered that only smsc75xx and smsc95xx calls usbnet_read_cmd()
and usbnet_write_cmd() inside its resume and suspend callback, the
patcheset introduce the nopm version of the two functions which
should be called only in the resume and suspend callback. So we
can solve the problem by runtime resuming device before doing
control message things.

Hi,

I am happy with these patches.
Dave, do you have a principal objection regarding these patches, too?

There were review comments and the most recently posted series
needs to be reposted with that feedback incorporated.
