From: Justin P. Mattock on 14 Jun 2010 16:30 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.
