Smatch complains about: e5e9f44c2 i2c: Drop I2C_CLIENT_INSMOD_2 to 8
The original define had an "any_chip", but this patch removed it.
-#define I2C_CLIENT_INSMOD_8(chip1, chip2, chip3, chip4, chip5, chip6, chip7, chip8) \
-enum chips { any_chip, chip1, chip2, chip3, chip4, chip5, chip6, \
- chip7, chip8 }
This causes some buffer under runs.
drivers/hwmon/fschmd.c +1040 fschmd_detect(33) warn: array offset '(kind-1)' can be negative (-1)
drivers/hwmon/tmp401.c +527 tmp401_detect(37) warn: array offset '(kind-1)' can be negative (-1)

(From a test version of smatch).
