HID: hid-sensor-custom: set fixed size for custom attributes
[ Upstream commit 9d013910df22de91333a0acc81d1dbb115bd76f6 ] This is no bugfix (so no Fixes: tag is necessary) as it is taken care of in hid_sensor_custom_add_attributes(). The motivation for this patch is that: hid_sensor_custom_field.attr_name and hid_sensor_custom_field.attrs has the size of HID_CUSTOM_TOTAL_ATTRS and used in same context. We compare against HID_CUSTOM_TOTAL_ATTRS when looping through hid_custom_attrs. We will silent the smatch error: hid_sensor_custom_add_attributes() error: buffer overflow 'hid_custom_attrs' 8 <= 10 Signed-off-by: Marcus Folkesson <marcus.folkesson@gmail.com> Acked-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz> Signed-off-by: Sasha Levin <sashal@kernel.org>
