From 59882c7f6714141300882af3d39ca6ffecf54ec2 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sun, 20 Nov 2022 10:34:41 +0100 Subject: hwmon: (gsc-hwmon) Switch to flexible array to simplify code Using flexible array is more straight forward. It - saves 1 pointer in the 'gsc_hwmon_platform_data' structure - saves an indirection when using this array - saves some LoC and avoids some always spurious pointer arithmetic Signed-off-by: Christophe JAILLET Link: https://lore.kernel.org/r/61a23e1d642397cfcecc4ac3bb0ab485d257987d.1668936855.git.christophe.jaillet@wanadoo.fr Signed-off-by: Guenter Roeck --- drivers/hwmon/gsc-hwmon.c | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) (limited to 'drivers/hwmon') diff --git a/drivers/hwmon/gsc-hwmon.c b/drivers/hwmon/gsc-hwmon.c index b60ec95b5edb..73e5d92b200b 100644 --- a/drivers/hwmon/gsc-hwmon.c +++ b/drivers/hwmon/gsc-hwmon.c @@ -257,13 +257,10 @@ gsc_hwmon_get_devtree_pdata(struct device *dev) if (nchannels == 0) return ERR_PTR(-ENODEV); - pdata = devm_kzalloc(dev, - sizeof(*pdata) + nchannels * sizeof(*ch), + pdata = devm_kzalloc(dev, struct_size(pdata, channels, nchannels), GFP_KERNEL); if (!pdata) return ERR_PTR(-ENOMEM); - ch = (struct gsc_hwmon_channel *)(pdata + 1); - pdata->channels = ch; pdata->nchannels = nchannels; /* fan controller base address */ @@ -277,6 +274,7 @@ gsc_hwmon_get_devtree_pdata(struct device *dev) of_node_put(fan); + ch = pdata->channels; /* allocate structures for channels and count instances of each type */ device_for_each_child_node(dev, child) { if (fwnode_property_read_string(child, "label", &ch->name)) { -- cgit v1.2.3
