Subject: [PATCH] net/ethernet/freescale: Fix incorrect IS_ERR_VALUE macro usages
IS_ERR_VALUE macro should be used only with unsigned long type.
Especially it works incorrectly with unsigned shorter types on
64bit machines.
Fixes: 4c35630ccda5 ("[POWERPC] Change rheap functions to use ulongs instead of pointers")
