i2c i2c-7: adapter quirk: msg too long (addr 0x0033, size 1664, read)

Tested on Debian, kernel 5.10.0-22-amd64, i2c device: Melexis MLX90640 sensor

That's a long message for i2c. That driver has a much shorter limit. Older versions could do more, but then the chip can't report errors. You could try to roll back to commit bbdbc859c7 "Convert the whole driver to an MFD driver" and see if that works better.

Hi Frank, thanks for your response.

I just tried it... now it doesn't report errors, but it can't read from I2C.
