Subject: [PATCH 5.13 610/800] tty: nozomi: Fix a resource leak in an error handling function
From: Christophe JAILLET <christophe.jaillet@...adoo.fr>
[ Upstream commit 31a9a318255960d32ae183e95d0999daf2418608 ]
A 'request_irq()' call is not balanced by a corresponding 'free_irq()' in
the error handling path, as already done in the remove function.
Add it.
Fixes: 9842c38e9176 ("kfifo: fix warn_unused_result")
