[igt-dev] [PATCH i-g-t 0/7] Use device dependant module parameters

Rebased and fixed Jani's work. Patches which didn't change I did maintain
Jani's authorship. These changes match to my kernel where there is path
/sys/kernel/debug/dri/<device>/i915_params/

Special part is the search of 'default device' in patch
'use igt_params_set_save for igt_set_module_param*'. Don't know if it is
the most obvious way nor do I know will this work on non-Intel driver.

Patch #4 Jani had not added S-o-b, will be added if Jani comment.

Fixed issues pointed by Petri. Reading comments I wasn't certain on
concensus about the final naming so I didn't go change that for now.

Jani Nikula (4):
lib/params: add igt_params.c for module parameter access
lib/params: overhaul param saving
lib/params: add igt_params_open() which will return path
igt/params: add generic saving module parameter set

Juha-Pekka Heikkila (3):
lib/params: start renaming functions igt_params_*
igt/params: use igt_params_set_save for igt_set_module_param*
tests/gem_eio: switch to using igt_params_set()
