From: Jarkko Sakkinen
Date: Fri Jun 17 2016 - 10:40:15 EST


When running make C=2 M=drivers/char/tpm/

CHECK drivers/char/tpm//tpm_crb.c
drivers/char/tpm//tpm_crb.c:248:31: warning: incorrect type in return expression (different address spaces)
drivers/char/tpm//tpm_crb.c:248:31: expected void [noderef] <asn:2>*
drivers/char/tpm//tpm_crb.c:248:31: got void *
