Subject: Input: drivers/char/keyboard.c - use time_after
X-Git-Tag: v2.6.26-rc1~1062^2^2~8
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b39b04403bba4f807ee6e57ae2f4407187588fcd;p=linux-2.6

Input: drivers/char/keyboard.c - use time_after

The functions time_before, time_before_eq, time_after, and time_after_eq
are more robust for comparing jiffies against other values.
