Hi Wolfram,

Thanks for your comments.
I will fix all of them + build errors reported by build-bot in the V6.

Best regards,

Hi,

quoted

+config I2C_STM32F4
+     tristate "STMicroelectronics STM32F4 I2C support"
+     depends on ARCH_STM32  || COMPILE_TEST

Double space.

quoted

+#define STM32F4_I2C_MIN_FREQ         2
+#define STM32F4_I2C_MAX_FREQ         42

Those two must be unsigned to fix the build error (e.g. 2U) reported by
build-bot.

Also, I get the following build warnings:

  CC      drivers/i2c/busses/i2c-stm32f4.o
drivers/i2c/busses/i2c-stm32f4.c: In function ‘stm32f4_i2c_handle_rx_addr’:
drivers/i2c/busses/i2c-stm32f4.c:445:6: warning: variable ‘sr2’ set but not used [-Wunused-but-set-variable]
  u32 sr2;
      ^~~
drivers/i2c/busses/i2c-stm32f4.c: In function ‘stm32f4_i2c_isr_event’:
drivers/i2c/busses/i2c-stm32f4.c:496:41: warning: variable ‘sr2’ set but not used [-Wunused-but-set-variable]
  u32 real_status, possible_status, ien, sr2;

I assume those are reads to clear the register, so we really don't need
to save the value in a variable.

Rest is looking good.

Thanks,

   Wolfram
