    Subject[PATCH 5.4 360/389] cxl: Fix a memory leak in an error handling path
    Date
    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().
