[PATCH 4/6] staging: comedi: Remove set but not used variable 'data'

[zhengbin]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/staging/comedi/drivers/dt2814.c: In function dt2814_interrupt:
drivers/staging/comedi/drivers/dt2814.c:193:6: warning: variable data set but not used [-Wunused-but-set-variable]

It is not used since commit 7806012e97ed ("staging:
comedi: refactor dt2814 driver and use module_comedi_driver")
