strsep() is a non-standardized API (by C or POSIX) and thus it is
non-portable between different operating systems. Replace it with
strtok_r() which is standardized by the C standard, and hence also by
POSIX.
The replacement occurs in the code that extracts individual PCI class
names (e.g. class=net:vdpa:foo:bar).
