i2c-stm32f4: remove redundant initialization of pointer reg
The pointer reg is assigned a value that is never read, it is later overwritten with a new value, hence the redundant initialization can be removed. Cleans up clang warning: drivers/i2c/busses/i2c-stm32f4.c:352:16: warning: Value stored to 'reg' during its initialization is never read Signed-off-by: Colin Ian King <colin.king@canonical.com> Acked-by: Alexandre TORGUE <alexandre.torgue@st.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
