Sorry, I forgot to refer to the memstick_check() memleak in drivers/memstick/core/memstick.c,
also discovered through CONFIG_KMEMLEAK=y option enabled.

The 4.16 is the last kernel I managed to start on my Lenovo desktop box which only reproduced
the memstick_check() leak.

Needless to say, this is not a i915-related bug.

Sorry for imprecision in my paragraph.

Mirsad
