Subject: rt2x00: add copy of clk for soc devices
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=34db70b92faed22f59fdc1dba766e8cb6248fe9e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

rt2x00: add copy of clk for soc devices

Since clk_get() is not trivial add copy of clk pointer to rt2x00dev
for System On Chip devices and initialize it on probe routine.
