[igt-dev] [PATCH v2 00/77] Ensure that file descriptors will be closed on exit

[Mauro Carvalho Chehab <mauro.chehab@linux.intel.com>]

From: Mauro Carvalho Chehab <mchehab@kernel.org>

GCC is usually smart enough to close devices on exit, but that doesn't work
with the logic inside igt_skip(), as it uses longjmp, causing the code to
go out of scope. Such scoped variables must be tracked in an outer scope to
the skipping subtest.

Change the logic on IGT tests in order to avoid keeping device opened at
the end of the test.

v2:
  - use volatile for file descriptors at patch 01  to avoid an undefined behavior;
  - added 3 more "close device on exit" patches that were missed at v1.
