[PATCH] char: remove unused variable res to clean up build warning

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Commit f368ed6088ae9 ("char: make misc_deregister a void function")
did not remove unused variable res and now we get a build warning:

drivers/rtc/rtc-ds1374.c: In function 'ds1374_remove':
drivers/rtc/rtc-ds1374.c:667:6: warning: unused variable 'res' 
[-Wunused-variable]
  int res;

simply remove this unused variable.
