Commit 5c4e8d3781bc ("usb: host: xhci-tegra: Add support for XUSB
context save/restore") is using the IPFS 'num_offsets' value when
allocating memory for FPCI context instead of the FPCI 'num_offsets'.
We have not observed any specific issues because of this, but could
cause too much memory or too little memory to be allocated. Fix this
by using the FPCI 'num_offsets' for allocating the FPCI memory for
storing the FPCI state.Cc: [email protected] Fixes: 5c4e8d3781bc ("usb: host: xhci-tegra: Add support for XUSB context save/restore") Signed-off-by: Jon Hunter <[email protected]> --- drivers/usb/host/xhci-tegra.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/usb/host/xhci-tegra.c b/drivers/usb/host/xhci-tegra.c index 9ce28ab47f4b..014d79334f50 100644 --- a/drivers/usb/host/xhci-tegra.c +++ b/drivers/usb/host/xhci-tegra.c @@ -856,7 +856,7 @@ static int tegra_xusb_init_context(struct tegra_xusb *tegra) if (!tegra->context.ipfs) return -ENOMEM; - tegra->context.fpci = devm_kcalloc(tegra->dev, soc->ipfs.num_offsets, + tegra->context.fpci = devm_kcalloc(tegra->dev, soc->fpci.num_offsets, sizeof(u32), GFP_KERNEL); if (!tegra->context.fpci) return -ENOMEM; -- 2.17.1
