[PATCH] staging: greybus: fix missing newline in sysfs_emit() format strings

[tuxdevv]

From: Deniz Gözen <denizgozen61@gmail.com>

The show functions for the audio module's name, vid, pid, intf_id,
ip_devices and op_devices sysfs attributes pass format strings to
sysfs_emit() without a trailing newline. Per sysfs conventions each
attribute should return content terminated by '\n', and checkpatch.pl
flags all six calls as missing the terminator.

Add the missing '\n' to each format string.
