Oliver Hartkopp 31cde3bdad can: isotp: isotp_sendmsg(): fix return error fix on TX path ... commit e38910c007 upstream. With commit d674a8f123 ("can: isotp: isotp_sendmsg(): fix return error on FC timeout on TX path") the missing correct return value in the case of a protocol error was introduced. But the way the error value has been read and sent to the user space does not follow the common scheme to clear the error after reading which is provided by the sock_error() function. This leads to an error report at the following write() attempt although everything should be working.
