Tomi Valkeinen 1cf8ddccbd media: i2c: ds90ub953: Fix use of uninitialized variables 
smatch reports some uninitialized variables:

drivers/media/i2c/ds90ub953.c:655 ub953_log_status() error: uninitialized symbol 'gpio_local_data'.
drivers/media/i2c/ds90ub953.c:655 ub953_log_status() error: uninitialized symbol 'gpio_input_ctrl'.
drivers/media/i2c/ds90ub953.c:655 ub953_log_status() error: uninitialized symbol 'gpio_pin_sts'.

These are used only for printing debug information, and the use of an
uninitialized variable only happens if an i2c transaction has failed,
which will print an error. Thus, fix the errors just by initializing the
variables to 0.
