Subject: [PATCH] devlink: Fix binary values print
Fix function pr_out_binary_value() to start printing the binary buffer
from offset 0 instead of offset 1. Remove redundant new line at the
beginning of the output
Example:
With patch:
mlx5e_txqsq:
05 00 00 00 05 00 00 00 01 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 8e 6e 3a 13 07 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
