Subject: thermal/intel_powerclamp: fix truncated kthread name
X-Git-Tag: v4.19.36~89

thermal/intel_powerclamp: fix truncated kthread name

[ Upstream commit e925b5be5751f6a7286bbd9a4cbbc4ac90cc5fa6 ]

kthread name only allows 15 characters (TASK_COMMON_LEN is 16).
Thus rename the kthreads created by intel_powerclamp driver from
"kidle_inject/ + decimal cpuid" to "kidle_inj/ + decimal cpuid"
to avoid truncated kthead name for cpu 100 and later.
