Subject: [PATCH v2 0/2] static_call: Fix two wild-memory-access bugs in static_call_del_module()

In __static_call_init(), any one of the kzalloc fails will cause
wild-memory-access when traverse the site and subsequent sites in
static_call_del_module().

Changes in v2:
- Add a new patch which fix a a similar problem.
- Update the commit message and simplify error stack for the first.

Jinjie Ruan (2):
  static_call: Fix a wild-memory-access bug in static_call_del_module()
  static_call: Fix a wild-memory-access bug when
    static_call_key_sites(key) is true
