[PATCH 1/2] asus_acpi: fix proc files parsing

[Alexey Dobriyan <adobriyan@gmail.com>]

From: Darren Jenkins <darrenrjenkins@gmail.com>

ICC complains about a "Pointless comparsion of unsigned interger with
zero" @ line 760 & 808 of asus_acpi.c

parse_arg() mentioned below returns -E but it's copied into unsigned variable...
