6.6-stable review patch. If anyone has any objections, please let me know.

------------------

From: Richard Fitzgerald <rf@opensource.cirrus.com>

[ Upstream commit 003ce8c9b2ca28fbb4860651e76fb1c9a91f2ea1 ]

In cs35l56_hda_posture_put() assign ucontrol->value.integer.value[0] to
a long instead of an unsigned long. ucontrol->value.integer.value[0] is
a long.

This fixes the sparse warning:

sound/hda/codecs/side-codecs/cs35l56_hda.c:256:20: warning: unsigned value
that used to be signed checked against zero?
sound/hda/codecs/side-codecs/cs35l56_hda.c:252:29: signed value source
