Subject: [PATCH v4 linux-next] usb:typec:mux: remove indentation for common path
Date: Wed, 24 Apr 2024 22:57:16 +0530

Nitpick, Mostly common path will not be indented.  so rewritten this 
function to check device_node pointer is null and removed common path 
indentation.

Signed-off-by: sundar <prosunofficial@gmail.com>

Fixed nitpicks in code according to comments received on other patch as
below:

[ Nit, this function should be rewritten to not work like this, the
"common" path should not be indented, but only the exception (i.e. bail
if ep is not allocated properly.) ]
https://lore.kernel.org/all/2024041103-doornail-professor-7c1e@gregkh/

Goal is to get rid of of_node_put,but sending this patch first to do one
thing at a time.

Changes since v1 - fixed the typo error for spell from identation to
indentation

Changes since v2 - Shifted the indentation to one level left for the
switch cases as per coding style.

Changes since v3 - Added descriptive subject for the patch and checked
from and sign-off having same name.
