[PATCH 4/8]drivers:tmp.c Fix warning: variable 'rc' set but not used

From: Justin P. Mattock
Date: Mon Jun 14 2010 - 16:28:19 EST

Im getting this warning when compiling:
CC drivers/char/tpm/tpm.o
drivers/char/tpm/tpm.c: In function 'tpm_gen_interrupt':
drivers/char/tpm/tpm.c:508:10: warning: variable 'rc' set but not used

The below patch gets rid of the warning,
but I'm not sure if it's the best solution.
