[media] r820t: Remove a warning for an unused value
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. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
