From f42b773a39d549f1ea922f6e4b65a8a135fcac17 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Mon, 21 Jul 2014 13:37:37 +0200 Subject: [PATCH] usb: phy: tegra: Avoid use of sizeof(void) commit 9ce9ec95fb9b82e09b55a52f1bb8a362bf8f74d8 upstream. The PHY configuration is stored in an opaque "config" field, but when allocating the structure, its proper size needs to be known. In the case of UTMI, the proper structure is tegra_utmip_config of which a local variable already exists, so we can use that to obtain the size from. Fixes the following warning from the sparse checker: drivers/usb/phy/phy-tegra-usb.c:882:17: warning: expression using sizeof(void) Fixes: 81d5dfe6d8b3 (usb: phy: tegra: Read UTMIP parameters from device tree) Signed-off-by: Thierry Reding Signed-off-by: Felipe Balbi Signed-off-by: Greg Kroah-Hartman --- drivers/usb/phy/phy-tegra-usb.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/usb/phy/phy-tegra-usb.c b/drivers/usb/phy/phy-tegra-usb.c index bbe4f8e..8834b70 100644 --- a/drivers/usb/phy/phy-tegra-usb.c +++ b/drivers/usb/phy/phy-tegra-usb.c @@ -881,8 +881,8 @@ static int utmi_phy_probe(struct tegra_usb_phy *tegra_phy, return -ENOMEM; } - tegra_phy->config = devm_kzalloc(&pdev->dev, - sizeof(*tegra_phy->config), GFP_KERNEL); + tegra_phy->config = devm_kzalloc(&pdev->dev, sizeof(*config), + GFP_KERNEL); if (!tegra_phy->config) { dev_err(&pdev->dev, "unable to allocate memory for USB UTMIP config\n"); -- 2.7.4
