[media] r820t: Remove a warning for an unused value
Mauro Carvalho Chehab [Thu, 25 Apr 2013 18:40:21 +0000 (15:40 -0300)]
Currently, the driver complains about the pre_detect var:

drivers/media/tuners/r820t.c: In function 'r820t_sysfreq_sel':
drivers/media/tuners/r820t.c:722:31: warning: variable 'pre_dect' set but not used [-Wunused-but-set-variable]

While rtl8232 code comments it, perhaps some other driver may use.
So, the better is to keep the code there, allowing to enable it
via r820t config data.
