Subject: [PATCH 5.4 100/177] media: vimc: sen: remove unused kthread_sen field

From: Dafna Hirschfeld <dafna.hirschfeld@...labora.com>

commit 3ea35d5db448c27807acbcc7a2306cf65c5e6397 upstream.

The field kthread_sen in the vimc_sen_device is
not set and used. So remove the field and
the code that check if it is non NULL
