leds: Remove incorrect use of preempt_count() from leds-gpio
leds: Fix potential leds-gpio oops
Some time ago it turned out that our suspend code ordering broke some
NVidia-based systems that hung if _PTS was executed with one of the PCI
devices, specifically a USB controller, in a low power state.
Then, it was noticed that the suspend code ordering was not compliant
with ACPI 1.0, although it was compliant with ACPI 2.0 (and later), and
it was argued that the code had to be changed for that reason (ref.
http://bugzilla.kernel.org/show_bug.cgi?id=9528).
So we did, but evidently we did wrong, because it's now turning out that
some systems have been broken by this change. Refs:
http://bugzilla.kernel.org/show_bug.cgi?id=10340
https://bugzilla.novell.com/show_bug.cgi?id=374217#c16
[ I said at that time that something like this might happend, but the
majority of people involved thought that it was improbable due to the
necessity to preserve the compliance of hardware with ACPI 1.0. ]
This actually is a quite serious regression from 2.6.24.
Moreover, the ACPI 1.0 ordering of suspend code introduced another issue
that I have only noticed recently. Namely, if the suspend of one of
devices fails, the already suspended devices will be resumed without
executing _WAK before, which leads to problems on some systems (for
example, in such situations thermal management is broken on my HP
nx6325). Consequently, it also breaks suspend debugging on the affected
systems.
Note also, that the requirement to execute _PTS before suspending
devices does not really make sense, because the device in question may
be put into a low power state at run time for a reason unrelated to a
system-wide suspend.
For the reasons outlined above, the change of the suspend ordering
should be reverted, which is done by the patch below.

These messages are a regression compared with 2.6.24, which did not
flood the syslog with them.
The actual underlying problem was introduced in 2.6.23, when somebody
made the string parsing no longer accept nul-terminated strings as a
valid input to store_uevent().
Eg. "add\0" was valid prior to 2.6.23, where the code regressed to
require "add" without the '\0'.
This patch fixes the 2.6.23 / 2.6.24 regressions, by having the code
once again tolerate the trailing '\0', if present.
According to GregKH, this mainly affects older Ubuntu systems, such as
the one I have here that requires this fix.

If "location" is > "addr_len" bits, the high bits of location would interfere
with the READ_CMD sent to the eeprom controller.
A patch was submitted to bug:
http://bugzilla.kernel.org/show_bug.cgi?id=4420
which simply truncated the "location", read whatever was in "location
modulo addr_len", and returned that value. That avoids confusing the
eeprom but seems like the wrong solution to me.
Correct would be to not read beyond "1 << addr_len" address of the eeprom.
I am submitting two changes to implement this:
1) tulip_read_eeprom will return zero (since we can't return -EINVAL)
if this is attempted (defensive programming).
2) In tulip_core.c, fix the tulip_read_eeprom caller so they don't
iterate past addr_len bits and make sure the entire tp->eeprom[]
array is cleared.
