Subject: [PATCH] media: i2c: ths7303: remove unused member driver_data

From: "Lad, Prabhakar" <prabhakar.csengg@...il.com>

This patch removes the driver_data member from ths7303_state structure.
The driver_data member was intended to differentiate between ths7303 and
ths7353 chip and get the g_chip_ident, But as of now g_chip_ident is
obsolete, so there is no need of driver_data.
