Subject: [IPX]: Use existing sock refcnt debugging infrastructure
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c2b42336f4a733020360157ba629d37f1410923a;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[IPX]: Use existing sock refcnt debugging infrastructure

Just like in the af_packet.c, the ipx_sock_nr variable is used
for debugging purposes.

Switch to using existing infrastructure. Thanks to Arnaldo for
pointing this out.
