From 0ee14725471cea66e03e3cd4f4c582d759de502c Mon Sep 17 00:00:00 2001 From: Jean-Philippe Brucker Date: Thu, 6 Jun 2024 15:46:09 +0100 Subject: mm/util: Swap kmemdup_array() arguments GCC 14.1 complains about the argument usage of kmemdup_array(): drivers/soc/tegra/fuse/fuse-tegra.c:130:65: error: 'kmemdup_array' sizes specified with 'sizeof' in the earlier argument and not in the later argument [-Werror=calloc-transposed-args] 130 | fuse->lookups = kmemdup_array(fuse->soc->lookups, sizeof(*fuse->lookups), | ^ drivers/soc/tegra/fuse/fuse-tegra.c:130:65: note: earlier argument should specify number of elements, later size of each element The annotation introduced by commit 7d78a7773355 ("string: Add additional __realloc_size() annotations for "dup" helpers") lets the compiler think that kmemdup_array() follows the same format as calloc(), with the number of elements preceding the size of one element. So we could simply swap the arguments to __realloc_size() to get rid of that warning, but it seems cleaner to instead have kmemdup_array() follow the same format as krealloc_array(), memdup_array_user(), calloc() etc. Fixes: 7d78a7773355 ("string: Add additional __realloc_size() annotations for "dup" helpers") Signed-off-by: Jean-Philippe Brucker Reviewed-by: Andy Shevchenko Link: https://lore.kernel.org/r/20240606144608.97817-2-jean-philippe@linaro.org Signed-off-by: Kees Cook --- drivers/soc/tegra/fuse/fuse-tegra.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'drivers') diff --git a/drivers/soc/tegra/fuse/fuse-tegra.c b/drivers/soc/tegra/fuse/fuse-tegra.c index b6bfd6729df3..d27667283846 100644 --- a/drivers/soc/tegra/fuse/fuse-tegra.c +++ b/drivers/soc/tegra/fuse/fuse-tegra.c @@ -127,8 +127,8 @@ static void tegra_fuse_print_sku_info(struct tegra_sku_info *tegra_sku_info) static int tegra_fuse_add_lookups(struct tegra_fuse *fuse) { - fuse->lookups = kmemdup_array(fuse->soc->lookups, sizeof(*fuse->lookups), - fuse->soc->num_lookups, GFP_KERNEL); + fuse->lookups = kmemdup_array(fuse->soc->lookups, fuse->soc->num_lookups, + sizeof(*fuse->lookups), GFP_KERNEL); if (!fuse->lookups) return -ENOMEM; -- cgit v1.2.3
