Subject: [PATCH] usb: chipidea: udc: Use usb_endpoint_is_isoc_in() rather than
 duplicating its implementation

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Tue, 24 Jun 2025 17:30:52 +0200

Reuse existing functionality from usb_endpoint_is_isoc_in() instead of
keeping duplicate source code.

The source code was transformed by using the Coccinelle software.
