s390/pkey: add missing __user annotations
Add missing __user annotations to get rid of a couple of sparse warnings. All callers actually pass kernel pointers instead of user space pointers, however the pointers are being used within KERNEL_DS. So everything is fine. Corresponding sparse warnings: drivers/s390/crypto/pkey_api.c:181:41: warning: incorrect type in assignment (different address spaces) expected char [noderef] <asn:1>*request_control_blk_addr got void *<noident> Cc: Harald Freudenberger <freude@linux.vnet.ibm.com> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
