Subject: [PATCH 00/12] clk: samsung: Use platform_driver_probe() to avoid
 __refdata

RFT/RFC because testing needed. I tried to do the same on exynos5-subcmu
and it caused weird oopses which even KASAN did not narrow. Probably
because of multiple exynos5-subcmu devices?

Switch registering platform driver to platform_driver_probe(), so the
'struct platform_driver' can be properly discarded after init and there
won't be need of __refdata to silence DEBUG_SECTION_MISMATCH.

The change requires using subsys_initcall instead of core_initcall,
because no device drivers would bound in the latter, as required by
platform_driver_probe().

Best regards,
Krzysztof
