Nicholas Piggin 7f2bf7840b tty: hvc: hvc_write() fix break condition ... Commit 550ddadcc7 ("tty: hvc: hvc_write() may sleep") broke the termination condition in case the driver stops accepting characters. This can result in unnecessary polling of the busy driver. Restore it by testing the hvc_push return code.
