From: Kees Cook Date: Tue, 24 Oct 2017 09:28:45 +0000 (-0700) Subject: iwlegacy: Convert timers to use timer_setup() X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=2b77839b37345693c565c835179c5f6f50a0ed77;p=openwrt%2Fstaging%2Fblogic.git iwlegacy: Convert timers to use timer_setup() In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly.
