Subject: loadb: Properly indicate aborted kermit transfer
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=515381414d5ce2032fbee6bb55206061660762bb;p=u-boot.git

loadb: Properly indicate aborted kermit transfer

When k_recv() returns zero it indicates that kermit transfer was aborted.
Function do_load_serial_bin() (caller of load_serial_bin()) interprets
value ~0 as aborted transfer, so properly propagates information about
aborted transfer from k_recv() to do_load_serial_bin().
