Carlos Sanchez ef0841e4cb can: slcan: allow reception of short error messages ... Allows slcan to receive short messages (typically errors) from the serial interface. When error support was added to slcan protocol in b32ff46685 ("can: slcan: extend the protocol with error info") the minimum valid message size changed from 5 (minimum standard can frame tIII0) to 3 ("e1a" is a valid protocol message, it is one of the examples given in the comments for slcan_bump_err() ), but the check for minimum message length prodicating all decoding was not adjusted. This makes short error messages discarded and error frames not being generated. This patch changes the minimum length to the new minimum (3 characters, excluding terminator, is now a valid message).
