X-Git-Tag: MMI-PSA29.97-13-9~16612^2~1226^2~53
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9978007befa5efdc16dc940631c594f420f96b09;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git

ASoC: soc-cache: Apply the cache_bypass option

Incorporate the use of the cache_bypass functionality in the
syncing functions.  The snd_soc_flat_cache_sync() need not be
hooked as there is no performance benefit from using the
cache_bypass option.
