From 332b32a23225e01cdfac4fb6cb1c76553f906cb5 Mon Sep 17 00:00:00 2001 From: Jerome Brunet Date: Mon, 12 Feb 2018 15:58:29 +0100 Subject: [PATCH] clk: meson: use devm_of_clk_add_hw_provider There is no remove callbacks in meson's clock controllers and of_clk_del_provider is never called if of_clk_add_hw_provider has been executed, introducing a potential memory leak. Fixing this by the using the devm variant. In reality, the leak would never happen since these controllers are never unloaded once in use ... still, this is worth cleaning.
