Subject: [PATCH v2] acpi: Use kstrtoul() instead of
strtoul()/simple_strtoul()
simple_strtoul() is deprecated; replace with kstrtoul() and
kstrtouint().
The ACPICA code is os-independent and cannot use these functions (at
least not directly).
Odd argument, given that kstrtoul() is used already in the acpi code.
They are not in the os-independent ACPICA code. The ACPI-related drivers are another story, since they are OS-dendent.
That this OS independent code mandates functions such as strtoul(),
which may not exist in a target OS, and that it maps strtoul() to
simple_strtoul() in a global include file, doesn't seem to be
correct either and is asking for repeated trouble. I would have
hoped that at the very least such mappings would be implemented
in local include files.
On the other side, my patch to remove the second global definition
of strtoul has been accepted, so the problem I was trying to solve
has been addressed elsewhere. With that, my patch is no longer needed
at this time, at least until someone else redefines strtoul().
Thanks,
Guenter
