[SCSI] target: Minor sparse warning fixes and annotations
This patch addresses the majority of sparse warnings and adds proper locking annotations. It also fixes the dubious one-bit signed bitfield, for which the signed one-bit types can be 0 or -1 which can cause a problem if someone ever checks if (foo->lu_gp_assoc == 1). The current code is fine because everyone just checks zero vs non-zero. But Sparse complains about it so lets change it. The warnings look like this: include/target/target_core_base.h:228:26: error: dubious one-bit signed bitfield Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Fubo Chen <fubo.chen@gmail.com> Signed-off-by: Nicholas A.
