X-Git-Tag: v5.15~9988^2~296
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c37631c7f686518157de4aa5fb456a54f27607b6;p=platform%2Fkernel%2Flinux-starfive.git

drivers/net: sxgbe: 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.
