[PATCH] net: fs_enet: Fix incorrect IS_ERR_VALUE macro usages

[Wei Li]

IS_ERR_VALUE macro should be used only with unsigned long type.
Especially it works incorrectly with unsigned shorter types on
64bit machines.

Fixes: 976de6a8c304 ("fs_enet: Be an of_platform device when CONFIG_PPC_CPM_NEW_BINDING is set.")
Fixes: 4c35630ccda5 ("[POWERPC] Change rheap functions to use ulongs instead of pointers")
