From bf21b6e44d0dd90846582249cc26230f249e6a63 Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Wed, 3 Jul 2019 20:10:33 +0200 Subject: [PATCH] lantiq: ltq-tapi: fix compatibility with Linux 4.15+ Linux 4.15 removes the init_timer() API. It's replaced by two functions: - timer_setup() is used instead of init_timer() and also replaces the timer "function" (callback) setup. - from_timer() has to be used to obtain the use-case specific data from a struct timer_list, which is now passed to the timer callback. Update the timer API to be compatible with Linux 4.15+ so it compiles with the upcoming Linux 4.19 kernel update.
