    Subject[PATCH 5.7 448/477] drm/amd/display: Use kvfree() to free coeff in build_regamma()
    Date
    From: Denis Efremov <efremov@linux.com>

    commit 81921a828b94ce2816932c19a5ec74d302972833 upstream.

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

    Fixes: e752058b8671 ("drm/amd/display: Optimize gamma calculations")
