Subject: ASoC: pxa-ssp: allow setting of dai format 0
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a5735b7ede1d1ca81ebf491d699530715b105560;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ASoC: pxa-ssp: allow setting of dai format 0

pxa_ssp_set_dai_fmt() currently has an early exit if the desired format
equals the current configuration. This is correct behaviour unless this
function is called with a zero value parameter for the first time.
Zero is a valid value for this function, but the early exit is bogus in
this case.

Hence, set priv->dai_fmt to -1 in the beginning so we can configure the
port.
