[PATCH] staging: greybus: audio: add newline to sysfs_emit() in show functions

[Adhyansh Verma]

Per Documentation/filesystems/sysfs.rst and kernel conventions, sysfs
show functions should terminate formatted attribute outputs with a
newline character.

Commit 14c91651df34 ("staging: greybus: audio: Use sysfs_emit in show
functions") converted sprintf() to sysfs_emit(), but left out the
trailing newlines. As a result, reading these attributes in userspace
outputs values without a line break and checkpatch warns that
sysfs_emit() formats should include a terminating newline.

Add the terminating newline to each sysfs_emit() format string in
audio_manager_module.c show callbacks.

Fixes: 14c91651df34 ("staging: greybus: audio: Use sysfs_emit in show functions")
