Subject: [PATCH] i2c: stm32f7: Make structure stm32f7_i2c_algo constant
Date: Thu, 15 Aug 2019 11:28:57 +0530 [thread overview]
Message-ID: <20190815055857.1944-1-nishkadg.linux@gmail.com> (raw)
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.
