Several update suggestions were taken into account
from static source code analysis.

Markus Elfring (46):
  Use kmalloc_array() in cond_init_bool_indexes()
  Delete an unnecessary return statement in cond_compute_av()
  Improve size determinations in four functions
  Use kmalloc_array() in hashtab_create()
  Adjust four checks for null pointers
  Use kcalloc() in policydb_index()
  Delete unnecessary variable assignments in policydb_index()
  Delete an unnecessary return statement in policydb_destroy()
  Delete an error message for a failed memory allocation in policydb_read()
  Move some assignments for the variable "rc" in policydb_read()
  Return directly after a failed next_entry() in genfs_read()
  Move assignments for two pointers in genfs_read()
  Move four assignments for the variable "rc" in genfs_read()
  One function call less in genfs_read() after null pointer detection
  One check and function call less in genfs_read() after error detection
  Move two assignments for the variable "rc" in filename_trans_read()
  Delete an unnecessary variable assignment in filename_trans_read()
  One function call less in filename_trans_read() after error detection
  Return directly after a failed next_entry() in range_read()
  Move four assignments for the variable "rc" in range_read()
  Two function calls less in range_read() after error detection
  Delete an unnecessary variable initialisation in range_read()
  Move an assignment for a pointer in range_read()
  Return directly after a failed kzalloc() in cat_read()
  Return directly after a failed kzalloc() in sens_read()
  Improve another size determination in sens_read()
  Move an assignment for the variable "rc" in sens_read()
  Return directly after a failed kzalloc() in user_read()
  Return directly after a failed kzalloc() in type_read()
  Return directly after a failed kzalloc() in role_read()
  Move an assignment for the variable "rc" in role_read()
  Return directly after a failed kzalloc() in class_read()
  Move an assignment for the variable "rc" in class_read()
  Return directly after a failed kzalloc() in common_read()
  Return directly after a failed kzalloc() in perm_read()
  Move an assignment for the variable "rc" in mls_read_range_helper()
  Move an assignment for the variable "rc" in policydb_load_isids()
  One function call less in five functions after null pointer detection
  Move two assignments for the variable "rc" in ocontext_read()
  Return directly after a failed kzalloc() in roles_init()
  Move two assignments for the variable "rc" in roles_init()
  One function call less in roles_init() after error detection
  Use kmalloc_array() in sidtab_init()
  Adjust two checks for null pointers
  Use common error handling code in sidtab_insert()
  Use seq_puts() in sel_avc_stats_seq_show()
