Subject: i2c: Do earlier driver model init
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a10f9e7caf8d3028d8fb1d4c3d590492cde3df3e;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

i2c: Do earlier driver model init

Move I2C driver model init earlier in the boot sequence.

This avoids oopsing in statically linked systems when some
subsystems register I2C drivers in subsys_initcall() code,
but those subsystems are linked (and initialized) before I2C.
