Hi Ruan,
Just a nitpick here that does not affect my r-b...

can we rephrase the whole commit to:
i2c: stm32: Do not check for 0 return after calling platform_get_irq()
It is not possible for platform_get_irq() to return 0. Use the
return value from platform_get_irq().
Two notes on the commit log:
- Use capital letter after "i2c: stm32: Fix..."
- This is not a fix, so that we shouldn't use the word "fix" in
the title.
just little notes for future patches :)
Thanks,
Andi
