[PATCH] ALSA: hda: cs35l56: Fix signedness error in cs35l56_hda_posture_put()

[Richard Fitzgerald]

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
