From: Roel Kluin Date: Fri, 13 Mar 2009 23:04:12 +0000 (-0700) Subject: x25: '< 0' and '>= 0' test on unsigned X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8db09f26f912f7c90c764806e804b558da520d4f;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git x25: '< 0' and '>= 0' test on unsigned skb->len is an unsigned int, so the test in x25_rx_call_request() always evaluates to true. len in x25_sendmsg() is unsigned as well. so -ERRORS returned by x25_output() are not noticed.
