Subject: ASoC: wm8904: Move register default setup into I2C probe()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=725e7a7b58fb27d8f97a1c4eae47cb5d37564725;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ASoC: wm8904: Move register default setup into I2C probe()

Get it done as early as possible, it's neater and minimises the time the
pins aren't configured as requested.
