Subject: [PATCH 5.4 148/152] drm/panfrost: Use kvfree() to free bo->sgts

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

commit 114427b8927a4def2942b2b886f7e4aeae289ccb upstream.

Use kvfree() to free bo->sgts, because the memory is allocated with
kvmalloc_array() in panfrost_mmu_map_fault_addr().

Fixes: 187d2929206e ("drm/panfrost: Add support for GPU heap allocations")
