Revision 9577fc5fdc8b07b891709af6453545db405e24ad authored by Michael Walle on 27 June 2022, 17:06:43 UTC, committed by David S. Miller on 29 June 2022, 13:05:00 UTC
Don't print a misleading header length mismatch error if the i2c call returns an error. Instead just return the error code without any error message.
