cdfabd20ed scst_lib: Remove a superfluous if-condition 
Since earlier code dereferences res->tgt_dev, res->tgt_dev can't be
NULL when the if (res->tgt_dev) code is reached. Hence remove the
if (res->tgt_dev != NULL) check.

26d7fd0e3a scst: Do not suspend SCSI command processing when adding a device

a device (scst_dev_list) is consistently protected by scst_mutex, suspending
command processing when adding a device is not necessary.

08e532715d Remove procfs support 
Since all RHEL/CentOS 5 users have upgraded to a newer version, procfs
support is no longer necessary. Hence remove procfs support. This patch
has been generated as follows:

git grep -lw CONFIG_SCST_PROC iscsi-scst qla2x00t scst scst_local srpt |\
  while read f; do
    echo ${f}
    unifdef -U CONFIG_SCST_PROC ${f} >${f}.out
    mv ${f}.out ${f}
  done

followed by two small manual edits in scst/include/scst.h and also in
qla2x00t/qla2x00-target/qla2x00t.c.
