+Subject: ata: libata: Fix memory leak for error path in ata_host_alloc()
+
+From: Zheng Qixing <zhengqixing@huawei.com>
+
+commit 284b75a3d83c7631586d98f6dede1d90f128f0db upstream.
+
+In ata_host_alloc(), if devres_alloc() fails to allocate the device host
+resource data pointer, the already allocated ata_host structure is not
+freed before returning from the function. This results in a potential
+memory leak.
+
+Call kfree(host) before jumping to the error handling path to ensure
+that the ata_host structure is properly freed if devres_alloc() fails.
+
+Fixes: 2623c7a5f279 ("libata: add refcounting to ata_host")

+Subject: irqchip/gic-v2m: Fix refcount leak in gicv2m_of_init()
+
+From: Ma Ke <make24@iscas.ac.cn>
+
+commit c5af2c90ba5629f0424a8d315f75fb8d91713c3c upstream.
+
+gicv2m_of_init() fails to perform an of_node_put() when
+of_address_to_resource() fails, leading to a refcount leak.
+
+Address this by moving the error handling path outside of the loop and
+making it common to all failure modes.
+
