Subject: net/ipv4: replace simple_strtoul with kstrtoul
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=413c27d8697751f72d2d6cf289140a8e060a8032;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

net/ipv4: replace simple_strtoul with kstrtoul

Replace simple_strtoul with kstrtoul in three similar occurrences, all setup
handlers:
* route.c: set_rhash_entries
* tcp.c: set_thash_entries
* udp.c: set_uhash_entries

Also check if the conversion failed.
