-Subject: [PATCH 2/2] linux-serial-test.c: fix potential hang in while loop
-
-process_read_data() assumes that we can always wait for reception
-of 1024 chars. However that is not true if one sets the number of
-chars with the '-w' cmdline parameter or chars are lost. Maybe there
-are other reasons.
-
-Replace the magic number of 1024 by calculating the number of expected
-chars from _cl_tx_bytes.
-
-Brake a possible infinite while loop by adding a timeout to the loop
-calculated from the expected chars times chartime.
-
-Upstream-Status: Submitted [https://github.com/cbrake/linux-serial-test/pull/61/]
-Fixes: 7fd1057f8a95 ("Add loop to read all data in rcv buffer")
