[PATCH 00/17] Fix various coverity warnings

[Simon Glass]

This series includes fixes for various coverity warnings reported in
recent months.

Unfortunately I am not sure how to fix the clock problems, as the fix
produces test failures, so the last two patches are marked RFC. I hope
that Stephen or Jean-Jacques can take a look.


Simon Glass (17):
  sandbox: net: Ensure host name is always a valid string
  video: Check return value in pwm_backlight_of_to_plat()
  sandbox: Indicate NULL-pointer access in 'sigsegv' command
  test: Rename final check in setexpr_test_backref()
  tools: Avoid showing return value of clock_gettime()
  reset: Avoid a warning in devm_reset_bulk_get_by_node()
  reset: Avoid a warning in devm_regmap_init()
  test: Avoid random numbers in dm_test_devm_regmap()
  dm: core: Check uclass_get() return value when dumping
  sandbox: scmi: Indicate dead code for coverity
  sandbox: cros_ec: Update error handling when reading matrix
  cbfs: Check offset range when reading a file
  pinctrl: Avoid coverity warning when checking width
  tpm: Check outgoing command size
  sandbox: Silence coverity warning in state_read_file()
  clk: Detect failure to set defaults
  RFC: clk: Return error code from clk_set_default_get_by_id()
