Subject: ASoC: wm5110: Use async writes
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=959e4083cd9c43fb3e818984926f9c590ee0aa2b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ASoC: wm5110: Use async writes

When writing the patch write to the device asynchronously, allowing better
performance when used with a bus like SPI which supports this by
minimising the need to context switch back to the driver to get the
next bit of data.
