[PATCH] staging: greybus: audio_manager_module: Add missing newlines to sysfs_emit() formats

[Ronit Gupta]

According to Documentation/filesystems/sysfs.rst, sysfs attribute values
should terminate with a single newline character.

Add missing trailing '\n' characters to the format strings of all
sysfs_emit() calls in gb_audio_module_*_show() attribute callbacks.

Please slow down...

Anyway, see my previous response.  This potentially breaks the API
so we can't do it.  Search lore.kernel.org for the function name for
more details.

The original patch never made it to lore, but check if someone already
sent this.

Something went really wrong here, please take a look at the email
documentation in the kernel for more details on how to do this properly.
