Blackfin: Add missing __user annotations to put_user
typeof() will not inherit the __user annotation so we have to explicitly specify this for '_p'. This fixes the following and quite a few similar warnings from spatch: kernel/sys.c:884:26: warning: incorrect type in initializer (different address spaces) kernel/sys.c:884:26: expected unsigned int *_p kernel/sys.c:884:26: got unsigned int [noderef] [usertype] <asn:1>*ruidp kernel/sys.c:885:26: warning: incorrect type in initializer (different address spaces) kernel/sys.c:885:26: expected unsigned int *_p kernel/sys.c:885:26: got unsigned int [noderef] [usertype] <asn:1>*euidp kernel/sys.c:886:26: warning: incorrect type in initializer (different address spaces) kernel/sys.c:886:26: expected unsigned int *_p kernel/sys.c:886:26: got unsigned int [noderef] [usertype] <asn:1>*suidp Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Bob Liu <lliubbo@gmail.com>
