scripts/gdb: decode bytestream on dmesg for Python3

The recent fixes to lx-dmesg, now allow the command to print successfully on Python3, however the python interpreter wraps the bytes for each line with a b'<text>' marker. To remove this, we need to decode the line, where .decode() will default to 'UTF-8' Link: http://lkml.kernel.org/r/d67ccf93f2479c94cb3399262b9b796e0dbefcf2.1462865983.git.jan.kiszka@siemens.com Signed-off-by: Kieran Bingham <[email protected]> Acked-by: Dom Cote <[email protected]> Tested-by: Dom Cote <[email protected]> Signed-off-by: Jan Kiszka <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
