Subject: [PATCH v2] kernel/sched: removed unused *cpumask ptr in kernel/sched/sched.h

From: Adi Gollamudi <adigollamudi@...il.com>

v2: fix formatting and style errors found by checkpatch.pl. no actual functional changes

v1: remove use of cpumask ptr initialized at the top of the mm_cid_get() function to nothing.
remove initialization of cpumask ptr in the same function, "cpumask = mm_cidmask(mm);" because
it is not used later.
