From 2252c3172cc5ecfab5aef1057f7c57b39e485f21 Mon Sep 17 00:00:00 2001 From: Nishka Dasgupta Date: Thu, 15 Aug 2019 11:28:57 +0530 Subject: i2c: stm32f7: Make structure stm32f7_i2c_algo constant Static structure stm32f7_i2c_algo, of type i2c_algorithm, is used only when it is assigned to constant field algo of a variable having type i2c_adapter. As stm32f7_i2c_algo is therefore never modified, make it const as well to protect it from unintended modification. Issue found with Coccinelle.
