'struct i2c_algorithm' are not modified in these drivers. Constifying this structure moves some data to a read-only section, so increase overall security, especially when the structure holds some function pointers. More over, dvb_usb_device_properties->i2c_algo seems to only be copied in i2c_adapter->algo, which is already a "const struct i2c_algorithm". This is done in dvb_usbv2_i2c_init() On a x86_64, with allmodconfig, as an example: Before: ====== text data bss dec hex filename 35366 5832 36 41234 a112 drivers/media/usb/dvb-usb-v2/af9015.o After: ===== text data bss dec hex filename 35430 5768 36 41234 a112 drivers/media/usb/dvb-usb-v2/af9015.o Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> |
