Subject: [PATCH net] net: stmmac: dwc-qos-eth: use devm_kzalloc() for AXI data
Date: Wed, 12 Mar 2025 19:43:09 +0000 [thread overview]
Message-ID: <E1tsRyv-0064nU-O9@rmk-PC.armlinux.org.uk> (raw)
Everywhere else in the driver uses devm_kzalloc() when allocating the
AXI data, so there is no kfree() of this structure. However,
dwc-qos-eth uses kzalloc(), which leads to this memory being leaked.
Switch to use devm_kzalloc().
Fixes: d8256121a91a ("stmmac: adding new glue driver dwmac-dwc-qos-eth")
