[BlueZ PATCH 0/9] Fix unchecked return value

[Tedd Ho-Jeong An]

From: Tedd Ho-Jeong An <tedd.an@intel.com>

This patch series fixes the unchecked return value(CWE-252) issues
reported by the Coverity scan.

The idea is to make the change as simple as possible without changing
the functional flow. So, it logs the output when the function fails
after checking the return value.

Tedd Ho-Jeong An (9):
  device: Fix unchecked return value
  adapter: Fix unchecked return value
  attrib-server: Fix unchecked return value
  plugins/admin: Fix unchecked return value
  profiles/a2dp: Fix unchecked return value
  profiles/input: Fix unchecked return value
  mesh: Fix unchecked return value
  obexd: Fix unchecked return value
  peripheral: Fix unchecked return value
