Subject: [PATCH 5.4 302/314] drm/amd/display: Use kvfree() to free coeff in build_regamma()

From: Denis Efremov <efremov@...ux.com>

commit 81921a828b94ce2816932c19a5ec74d302972833 upstream.

Use kvfree() instead of kfree() to free coeff in build_regamma()
because the memory is allocated with kvzalloc().
