Subject: [PATCH AUTOSEL 5.4 12/21] cxl: Fix a memory leak in an error handling path
Date: Sun, 14 Aug 2022 11:35:22 -0400 [thread overview]

From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
[ Upstream commit 3a15b45b5454da862376b5d69a4967f5c6fa1368 ]
A bitmap_zalloc() must be balanced by a corresponding bitmap_free() in the
error handling path of afu_allocate_irqs().
