From d761b9f21114478f9cc09f5c358a05be0870cc5d Mon Sep 17 00:00:00 2001 From: Adrian Schmutzler Date: Thu, 2 Apr 2020 19:52:00 +0200 Subject: broadcom-wl: fix compilation with kernel >= 4.15 Since kernel 4.15, init_timer is not available anymore, and has been replaced by timer_setup. The fixes compilation of wl_linuc.c, which returned the following errors beforehand (line-wrapped manually): .../broadcom-wl-5.10.56.27.3/driver/wl_linux.c: In function 'wl_init_timer': .../broadcom-wl-5.10.56.27.3/driver/wl_linux.c:2576:2: error: implicit declaration of function 'init_timer'; did you mean 'init_timers'? [-Werror=implicit-function-declaration] init_timer(&t->timer); ^~~~~~~~~~ init_timers .../broadcom-wl-5.10.56.27.3/driver/wl_linux.c:2577:10: error: 'struct timer_list' has no member named 'data' t->timer.data = (ulong) t; ^ .../broadcom-wl-5.10.56.27.3/driver/wl_linux.c:2578:20: error: assignment to 'void (*)(struct timer_list *)' from incompatible pointer type 'void (*)(ulong)' {aka 'void (*)(long unsigned int)'} [-Werror=incompatible-pointer-types] t->timer.function = wl_timer; This should fix build of several devices on bcm63xx with testing kernel (4.19).
