[PATCH -next 1/3] staging: vt6655: remove unused variable

[Edmundo Carmona Antoranz <eantoranz@gmail.com>]

Since its introduction in 5449c685a4b3 (Staging: Add pristine
upstream vt6655 driver sources, 2009-04-25), the values
stored in variable byData have never been read in the macro
PCAvDelayByIO. By removing it, we are getting rid of a warning:

drivers/staging/vt6655/upc.h:45:16: warning: variable ‘byData’ set but not used [-Wunused-but-set-variable]
